A 2 kg object moving at 10 m/s has a 4 n force applied to it. Can you predict how the force will affect the object?.

The pascal is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.

Answer:

the car’s final displacement is 60 m

Explanation:

Given;

initail velocity of the car, u = 0

acceleration of the car, a = 0.8 m/s²

time of motion, t = 10 s

The first displacement of the car:

\(x_1 = ut + \frac{1}{2} at^2\\\\x_1 = 0 + \frac{1}{2} (0.8)(10)^2\\\\x_1 = 40 \ m\)

The second displacement of the car;

acceleration, a = 0.4 m/s²,   time of motion, t = 10 s

\(x_2 = ut + \frac{1}{2} at^2\\\\x_2 = 0 + \frac{1}{2} (0.4)(10)^2\\\\x_2 = 20 \ m\)

The final displacement of the car;

x = x₁  +  x₂

x = 40 m  +  20 m

x = 60 m

Therefore, the car’s final displacement is 60 m

The highest ramp angle at which the crate can still be at rest is roughly 35.5 degrees.

To determine the maximum ramp angle that still allows the crate to remain at rest, you need to consider the balance of forces acting on the crate. When the crate is on the verge of slipping, the frictional force is equal to the component of gravitational force acting parallel to the ramp.

Given that the coefficient of friction (µ) is 0.7, you can use the formula for the frictional force:

Frictional force (F_friction) = µ * Normal force (F_N)

The normal force acting on the crate is the component of gravitational force acting perpendicular to the ramp, which can be calculated as:

F_N = m * g * cos(θ)

The gravitational force acting parallel to the ramp can be calculated as:

F_gravity_parallel = m * g * sin(θ)

At the maximum angle, the frictional force will be equal to the gravitational force acting parallel to the ramp:

µ * F_N = F_gravity_parallel

Now, substitute the known values:

0.7 * (m * g * cos(θ)) = m * g * sin(θ)

Since the mass (m) and gravitational acceleration (g) are the same on both sides of the equation, they can be canceled out:

0.7 * cos(θ) = sin(θ)

To find the maximum angle (θ), you can use the arctangent function:

θ = arctan(0.7)

θ ≈ 35.5 degrees

So, the maximum ramp angle that still allows the crate to remain at rest is approximately 35.5 degrees.

The equivalent resistance of two resistors wired in series is 14 ohms. The correct answer is option B. 14 ohms.


When resistors are connected in series, the total resistance is equal to the sum of the individual resistances. This can be represented by the equation:

Rt = R1 + R2

Where Rt is the total resistance, R1 is the resistance of the first resistor, and R2 is the resistance of the second resistor. In this case, R1 is 10 ohms and R2 is 4 ohms. Plugging these values into the equation gives:

Rt = 10 ohms + 4 ohms = 14 ohms

Therefore, the equivalent resistance of these two resistors is 14 ohms.

We can change a gas to liquid by decreasing the temperature and increasing the pressure.

Phase transition is the process by which a substance transforms from one state—solid, liquid, or gas—to another. Every element and substance has a precise range of temperatures and pressures at which it can change from one phase to another.

Each substance can transform into one of three phases: solid, liquid, or gas. At specific temperatures, every substance is in one of these three phases. The intermolecular forces acting on the material's molecules and atoms have a significant impact on the temperature and pressure at which the substance will change.

When we change a gas to liquid, we have to decrease in the temperature and increase in the pressure for this phase transition.

The mass of the planet is approximately 5.97 × 10²⁴ kg. Mass is a fundamental physical quantity that measures the amount of matter in an object. It is a scalar quantity and is measured in units such as kilograms (kg) or grams (g).

The mass of the planet can be calculated using the following formula:

M = (4π²r³)/(GT²)

where M is the mass of the planet, r is the radius of the orbit, T is the period of the orbit, G is the gravitational constant.

In this case, we have r = 3.0 × 10⁶ m, T = 6 h 44 min = 24240 s, and G = 6.6743 × 10⁻¹¹ N m²/kg²

First, we need to convert the period of the orbit to seconds:

6 h 44 min = 6 × 60 min + 44 min = 404 min = 24240 s

Now, we can plug in the values into the formula and solve for M:

M = (4π²r³)/(GT²)

M = (4π²(3.0 × 10⁶)³)/[(6.6743 × 10⁻¹¹)(24240)²]

The centripetal force (Fc) of the ball is 0.64N.

Centripetal force is the force on a rotating or orbiting body in the direction of the centre of rotation.

Centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path.

Centripetal force formula is given as the product of mass (in kg) and tangential velocity (in meters per second) squared, divided by the radius (in meters) as follows:

Fc = mv²/r

The term "initial velocity" refers to the velocity of an object at the beginning or starting point of a particular motion or event. The ball travels approximately 18.34 meters horizontally. The ball reaches a maximum height of approximately 5.45 meters.

In physics, velocity is a vector quantity, meaning it has both magnitude (speed) and direction. So the initial velocity includes information about the speed and the direction in which the object is moving. It is often denoted by the symbol "Vi" or "u" and is typically measured in units of meters per second (m/s) or any other appropriate unit of velocity.

To find the horizontal distance traveled by the ball, we can use the equation:

Horizontal distance = Initial velocity * Time * Cos(angle)

First, we need to convert the angle from degrees to radians, as trigonometric functions typically use radians. We have:

\(Angle (in radians) = Angle (in degrees) * \pi / 180\\ \theta = 30_0 * \pi / 180\\ \theta = 0.5236 radians\)

Now we can calculate the horizontal distance:

Horizontal distance = \(15.0 m/s * 1.50 s * Cos(0.5236)\)

Horizontal distance \(= 18.34 meters\)

Therefore, the ball travels approximately 18.34 meters horizontally.

To find the maximum height reached by the ball, we can use the equation for vertical displacement:

Vertical displacement = \(Vi * Sin( \theta) * t - 0.5 * g * t^2\)

Again, we need to convert the angle to radians:

\(\theta = 30_0 * \pi / 180 \theta = 0.5236 radians\)

Now we can calculate the vertical displacement:

Vertical displacement \(= 15.0 m/s * Sin(0.5236) * 1.50 s - 0.5 * 10 m/s^2 * (1.50 s)^2\)

Vertical displacement \(= 5.45 meters\)

Therefore, the ball reaches a maximum height of approximately 5.45 meters.

The axis of the Earth is tilted because of the way it was formed and the forces acting upon it.

The most widely accepted theory is that the Earth was formed about 4.5 billion years ago from the solar nebula, a rotating disk of gas and dust that surrounded the young Sun. As the disk began to cool and contract, it flattened into a disk, and the Earth formed within it. The gravitational forces of the Sun and Moon acting on the Earth caused it to become slightly flattened at the poles and bulging at the equator, and this resulted in a tilting of the Earth's axis. The tilt of the Earth's axis has remained relatively constant over time, leading to the seasons we experience as the Earth orbits the Sun.

(a) The support of K can be given by {0, 1, 2, 3, 4}.

(b) The set of events in which the aircraft is functioning can be given as follows: {K ≥ 1}, which means the aircraft is functioning if and only if at least one of its engines is functioning properly.

(c) Let's assume that the probability of each engine functioning properly is given by p. So, the probability of any particular engine malfunctioning or not functioning properly is (1 - p).

Since the aircraft is functioning if and only if at least one of its engines is functioning properly, the probability of system reliability can be calculated using the following formula:

P(K ≥ 1) = 1 - P(K = 0)

Since each engine functions independently of each other, the probability of each engine malfunctioning can be multiplied together. Thus, we have:

P(K = 0) = (1 - p)^4

Then,

P(K ≥ 1) = 1 - P(K = 0)

= 1 - (1 - p)^4

Therefore, the probability of the aircraft functioning, which represents system reliability, is given by 1 - (1 - p)^4.

When you walk at a constant velocity, you move forward with a steady speed and direction. The velocity is defined as the rate at which an object's position changes with respect to time. When you walk, you typically aim to move forward with a constant velocity, which is the speed at which you walk and the direction you walk. In certain situations, a constant velocity is ideal, such as when you are traveling long distances and want to arrive at your destination at a certain time.
