50m/s.

Explanation:

Answer:

\(V_f=50m/s\)

Explanation:

Use the the formula for final velocity (kinematic equation):

\(V_f=V_i+at\)

Final velocity = Initial velocity + acceleration times time

Given values:

Rest - indicates 0 initial velocity

Acceleration - 10 m/s^2

Time - 5 seconds

Insert the given values:

\(V_f=0+5\times10\)

\(V_f=50m/s\)

Car A travel four times farther than car B.

According to non-uniform motion

(v')² = v² + 2ad

(v')² = v² + 2ad

0² = v² + 2 × (- a) × d

0 = v² - 2ad

v² = 2ad

Compare car A and B

v₁²/v₂² = 2a₁d₁/2a₂d₂

(2v₂)²/v₂² = 2ad₁/2ad₂

4v₂²/v₂² = d₁/d₂

4/1 = d₁/d₂

When the light source is changed from red light to violet light in an interference pattern formed by passing light through a pair of narrow slits, the bright spots in the interference pattern will be closer together.

Interference patterns occur when light waves from different sources or parts of the same source interfere with each other constructively or destructively. In the case of a pair of narrow slits, the light passing through the slits diffracts and creates a pattern of bright and dark spots on a screen.

The spacing between the bright spots in the interference pattern is determined by the wavelength of the light used. The wavelength of light is inversely proportional to its color, with violet light having a shorter wavelength than red light.

When the light source is changed from red light to violet light, the wavelength of the light is decreased. As a result, the bright spots in the interference pattern will be closer together.

This is because the shorter wavelength of the violet light causes the wavefronts to compress, resulting in a smaller distance between adjacent bright spots.

In summary, changing the light source from red to violet light in an interference pattern formed by passing light through a pair of narrow slits will cause the bright spots in the interference pattern to be closer together.

Answer:

$108.90

Explanation:

step 1. multiply kw by rate of change ( 1.1kw x .11 = .121)

step 2. multiply the product above by the time use which is 30 mins in this case so .121 x 30 = 3.63

step 3. last step is to multiply the product you just got by the time per month soooo 3.63 times 30 days = 108.90 :)

The power charge of the dryer for a month for a period of 30 minutes every day will be 108.9 watts.

Electric power is the rate at which the electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one watt is equal to one joule per second.

The amount of power rate for one minute = 1.1 × 11/100 = 1.1 × 0.11 = 0.121 watts

The amount of power rate for 30 minutes = 0.121 × 30 = 3.63 watts

The power rate for 30 days = 3.63 × 30 = 108.9 watts

Therefore, the power charge for the month is 108.9 watts.

The main answer to the given question is -3.0 m/s.What is the explanation to the given question?Here, we need to find the ball's velocity relative to the ground at the instant of release.

So, let's assume that the upward direction is positive. Then, the velocity of the gondola (v₁) is -2.0 m/s (as it is moving in the opposite direction).The passenger throws the ball down at a speed of 5.0 m/s relative to his body. So, the velocity of the ball relative to the passenger (v₂) is -5.0 m/s (as it is thrown downwards).

Now, we can find the velocity of the ball relative to the ground (v₃) using relative velocity formula, which is:v₃ = v₂ + v₁v₃ = (-5.0) + (-2.0)v₃ = -7.0 m/sSo, the ball's velocity relative to the ground at that instant is -7.0 m/s. Therefore, the main answer is -3.0 m/s.

#SPJ11

The ball's velocity relative to the ground at the instant of release is 7.0 m/s.

1. The balloon-supported gondola is rising at a speed of 2.0 m/s. This means that the gondola and everything inside it, including the passenger and the ball, are moving upward with a velocity of 2.0 m/s relative to the ground.

2. The passenger in the gondola throws a small ball down at a speed of 5.0 m/s relative to his body. Since the passenger is moving upward with the gondola at 2.0 m/s, we need to consider the relative motion between the passenger and the ball.

3. When the passenger throws the ball downward, the ball's velocity relative to the passenger is 5.0 m/s downward.

4. To find the ball's velocity relative to the ground at the instant of release, we need to combine the velocity of the gondola (2.0 m/s upward) and the ball's velocity relative to the passenger (5.0 m/s downward).

5. Since the velocities are in opposite directions, we subtract the magnitudes: 5.0 m/s - 2.0 m/s = 3.0 m/s.

6. The negative sign indicates that the ball is moving downward relative to the ground.

7. Finally, to find the ball's overall velocity relative to the ground at the instant of release, we consider the magnitude only: |-3.0 m/s| = 3.0 m/s.

8. However, since the problem states that the ball's velocity is 5.0 m/s relative to the passenger's body, we need to take the direction into account. Thus, the ball's velocity relative to the ground at that instant is 3.0 m/s downward (or -3.0 m/s).

Therefore, the ball's velocity relative to the ground at the instant of release is 7.0 m/s.

The statement "the closer you get, the farther you are" is a paradox. It contradicts the basic law of physics that two objects cannot occupy the same space simultaneously. It is often used to describe a situation where two people who were once very close to each other have grown apart or become distant.

In other words, the more we try to get close to someone, the more distant we feel from them.This paradox highlights the emotional disconnect that can arise between two individuals even when they are physically close. It's not uncommon for two people in a relationship to start drifting apart after a while. This is because they start focusing on their differences instead of their similarities, which leads to misunderstandings and disagreements.

In conclusion, the closer you get, the farther you are, highlights the importance of emotional connection in any relationship. We must learn to look beyond our differences and focus on the things that bring us together.

At every location along the string, the amplitudes of two waves that interfere with one another are added. The two separate waves combine to form the final wave.

Two transverse waves are present in this instance, one traveling to the right and the other to the left. The waves will interact destructively when they meet since their motions are in opposition.

The resultant wave f(x) at any point x on the string may be calculated by summing the two amplitudes if we let f1(x) represent the amplitude of the wave going to the right and f2(x) represent the amplitude of the wave moving to the left:

f(x) = f1(x) + f2(x)

The amplitudes of the two waves will be equal in size and facing in opposite directions when they collide. As a result, the amplitude that results will be zero, and the string will then be at rest.

The resulting wave will alternate between constructive and destructive interference as the waves continue to travel past one another.

As a result, the string will develop a pattern of nodes (points of zero displacements) and antinodes (points of maximum displacement).

The combined frequency and wavelength of the various waves as well as the rate of wave propagation along the string will determine the final wave's frequency and wavelength.

In order to avoid injury to driver, The force constant of this spring should be 73.82 N/m

Calculation of force constant to this spring:

Here  

vertical drop is 15 m.

mass of the car, m= 113 kg

gravitational acceleration, g= -9.8 m/s^2

spring compression before car stops, x= 3.0 m

we need to use Hooke's law and Newton's second law:

F(net) = F(x)

m*a=-k*x

here a=g

k= -(m*g) / x

here k is force constant of this spring

When a metal ball is charged by induction using a negatively charged plastic rod, the charge acquired by the metal ball is positive.

This is because the negatively charged plastic rod attracts the positive charges in the metal ball, causing the negative charges to move away from the rod and towards the opposite end of the metal ball.

This leaves the end of the metal ball closest to the rod with a net positive charge, while the far end of the metal ball retains a net negative charge.

This separation of charges results in a positive charge on the end of the metal ball closest to the negatively charged rod.

The integral of 1/(1 + x²) is (1/2)ln|1 + x²| + C where C is the constant of integration.

Integration is a mathematical process of finding the antiderivative of a function. To integrate the given expression 1/(1 + x²), we will use the substitution method.

Let u = 1 + x², du/dx = 2x dx, then dx = du/2x and the integral becomes:

∫1/(1 + x²) dx = ∫1/u * (1/2x) du= (1/2)∫1/u du

The antiderivative of 1/u is ln|u| + C, where C is the constant of integration.

Therefore, the final solution of the integral is (1/2)ln|1 + x²| + C.

Let us work through the steps:

Step 1:Let u = 1 + x² and then differentiate both sides with respect to x to obtain du/dx. du/dx = 2x

Substitute 2x dx = du into the integral ∫1/(1 + x²) dx to get the integral in terms of u:∫1/u * (1/2x) du = (1/2) ∫1/u du

Step 2:Calculate the antiderivative of 1/u, which is ln|u|. Thus, the final solution is (1/2)ln|1 + x²| + C, where C is the constant of integration. The constant C will vary depending on the initial conditions of the problem.
