Newton’s law of motion can be divided by three types that is 1st law, 2nd law and 3rd law and it is law of gravity. The three laws are simple and sensible.

The first law states that a force must be applied to an object in order to change its velocity. When the object’s velocity is changing that mean it is accelerating, which implies a relationship between force and acceleration.

The second law, the acceration of an object is directly proportional to the net force acting on it and is inversely proportional to its mass. The direction of the acceleration is in the direction of the acceleration is in the direction of the net force acting on the object.

Finally, the third law, whenever we push on something, it pushes back with equal force in the opposite direction.

Answer:

Explanation:

Mechanical Advantage is defined as the ratio of force output with respect to the force input. Thus,

MA = output / input

MA = 5 / 25

MA = 1/5

MA = 0.2

Since this value is less then one. Even though it's tagged a mechanical advantage, in reality it would be mechanical disadvantage.

Therefore, we can say that the mechanical advantage of the baseball bat is 0.2

Answer:

The angle between two forces is 165 degrees.

Explanation:

We have,

Force 1, \(F_1=27\ N\)

Force 2, \(F_2=30\ N\)

Resultant of two forces, F = 8 N

It is required to find the angle between two forces. The resultant of two force is given by the formula as follows :

\(F=\sqrt{F_1^2+F_2^2+2F_1F_2\cos\theta}\)

\(\theta\) is the angle between F₁ and F₂

So,

\(F^2=F_1^2+F_2^2+2F_1F_2\cos\theta\\\\\cos\theta=\dfrac{F^2-F_1^2-F_2^2}{2F_1F_2}\\\\\cos\theta=\dfrac{(8)^2-(27)^2-(30)^2}{2\times 27\times 30}\\\\\cos\theta=-0.966\\\\\theta=\cos^{-1}\left(-0.966\right)=165^{\circ}\)

So, the angle between two forces is 165 degrees.

The final speed of the ball before it strikes the ground can be calculated using the equation of motion, considering that the initial velocity is 5 m/s, the initial height is 1.0 meter and acceleration due to gravity is 9.8 m/s^2. The equation of motion is given by:

v^2 = u^2 + 2as

where,

v = final velocity

u = initial velocity (5 m/s)

a = acceleration due to gravity (9.8 m/s^2)

s = height travelled (1.0 m)

Substituting the values, we get

v^2 = 5^2 + 2 * 9.8 * 1.0

v^2 = 25 + 19.6

v^2 = 44.6

v = sqrt(44.6)

So the final speed is v = 6.68 m/s

Hence, the final speed of the ball right before it strikes the ground is approximately 6.68 m/s.

Speed ​​is a derived quantity derived from the principal quantities of length and time, where the formula for speed is distance divided by time. Velocity is a vector quantity that indicates how fast an object is moving. The magnitude of this vector is called speed and is expressed in meters per second.

suppose you have a straight wire that has a resistance of 5 ohms and a length of 11 meters, attached to a battery. The U is 5 volts, to the nearest 0.01.

Using the given information, we can determine the current flowing through the wire when the maximum force is experienced. The formula for the force on a wire in a magnetic field is:

F = B * I * L * sin(theta)

Where F is the force, B is the magnetic field strength, I is the current, L is the length of the wire, and theta is the angle between the magnetic field and the current. In this case, the maximum force occurs when sin(theta) = 1 (i.e., when the angle is 90 degrees).

Given F = 11 N, B = 7 T, and L = 11 m, we can solve for I:

11 N = 7 T * I * 11 m
I = 11 N / (7 T * 11 m)
I = 1 A

Now that we know the current, we can use Ohm's Law (V = I * R) to find the battery voltage, where V is the voltage, I is the current, and R is the resistance:

V = 1 A * 5 Ohms
V = 5

Static equilibrium means that all forces are equal, so to make this easiest you want to break F1 into it's horizontal and vertical components. As there are no other forces acting in the horizontal, we know the horizontal component of F1 is 40N.

Dynamic equilibrium is a state in which bodies are moving at a constant speed as opposed to static equilibrium, which is a state in which bodies are at rest (rectilinear motion). The total amount of forces exerted on them in both situations is zero.

When two forces are acting on an object that is in static equilibrium, it indicates that their sum is zero, which makes static equilibrium a useful analytical tool. You may create an equation to figure out the direction and strength of the unknown force if you know the direction and strength of one of the forces.

Answer: a fuse wire is a wire of high resistance and low melting point.

The correct answer is: "d) speed, displacement". Speed and displacement are merely scalar. Speed is magnitude without direction, a scalar quantity. Displacement is a scalar quantity that only measures an object's position change.

The only scalar option is "d) speed, displacement." Scalar quantities can be described solely by their magnitude or numerical value. They have no vectors. Speed is a scalar quantity since it measures distance covered. It measures speed without direction.

Displacement means moving an object in a certain direction. Displacement is a scalar quantity if just the magnitude of the position shift is considered. Velocity is a vector quantity because it comprises magnitude (speed) and direction. It shows how fast an object changes direction. Momentum, the product of mass and velocity, is a vector quantity. Direction and magnitude. Therefore only "d) speed, displacement" is scalar since it includes speed (scalar) and disregards direction for displacement.

Explanation: When a liquid changes into a gas vaporization has occurred. The process can either occur due to boiling or evaporation. Boiling occurs when the vapor pressure of the liquid is raised (by heating) to the point where it is equal to the atmospheric pressure.

You can use thermal energy to change a liquid into a gas.

By virtue of its temperature, a system in a condition of thermodynamic equilibrium has thermal energy, or internal energy. Unlike the energy of systems that are not in a state of thermodynamic equilibrium, thermal energy cannot be transformed into meaningful work as quickly.

For instance, the same fluid or solid in a thermodynamic equilibrium state with the same energy (as thermal energy) cannot do work unless it is combined with another substance at a different temperature, as in a heat engine. However, the same fluid or solid in a moving state with the same energy (as mechanical energy) can be converted to work in some mechanical device, such as a windmill or a waterwheel.

Explanation:

Let's use trigonometry to find the elevation angle of the telescope, we assume that the rocket remains fixed in the telescope.

        tan θ = CO / CA

the adjacent leg is CA = 16 km = 16 10³ m

Let's use kinematics to find the height of the rocket

          v = y / t

          y = v t

this height is equal to the opposite leg

          CO = v t

we substitute

         tan θ = vt / 16

         tan θ = 1200/16 t

         tan θ = 75 t

         θ = tan⁻¹ ( 75 t )

speed is defined by

          w = dθ/dt

          w = \(\frac{1}{1 + (75 t)^2} \ 75\)  

as time increases we can neglect the 1 of the denominator

Yes, changing the length significantly affects the period of a pendulum. The length of a pendulum significantly affects its period, and the relationship between length and period is described by the formula T = 2π√(L/g).
Explanation:

A pendulum is a device that consists of a weight suspended from a pivot point that is free to oscillate back and forth when set in motion. The period of a pendulum refers to the time it takes for the pendulum to complete one oscillation. The period of a pendulum is directly proportional to its length, which means that if the length of a pendulum is increased, its period will increase as well. If the length of a pendulum is decreased, its period will decrease as well.

This relationship between length and period is described by the following formula T = 2π√(L/g) Where T = period of the pendulum L = length of the pendulum g = acceleration due to gravity Changing the length of a pendulum will cause its period to change because the length of the pendulum affects the distance it travels during each oscillation. A longer pendulum will travel a greater distance than a shorter pendulum, resulting in a longer period. On the other hand, a shorter pendulum will travel a shorter distance, resulting in a shorter period. In conclusion, the length of a pendulum significantly affects its period, and the relationship between length and period is described by the formula T = 2π√(L/g).
