Answer:
Kinetic Energy
Explanation:
The potential energy is being converted into kinetic energy. The hitter has struck the ball transferring the kinetic energy from the swinging bat to the ball.
Answer:
15.825 m
Explanation:
t = Time taken = 2.5 s
u = Initial velocity = 6.75 m/s
v = Final velocity = 5.91 m/s
s = Displacement
a = Acceleration
Equation of motion


The distance Rickey slides across the ground before touching the base is 15.825 m
Answer: energy source, path, and load
Explanation:
Answer:
The minimum force is required is, f = 0.3 mg Newton
Explanation:
Given data,
The coefficient of the static friction, μₓ = 0.3
Let the mass of the wheel is, m = M kg
The minimum force required to set the wheel in motion is equal to the force of static friction. This amount of force can be applied tangentially to the wheel in a vertical direction to set the wheel in motion.
<em> Fₓ = μₓ. F</em>
Where F is the normal force acting on the wheel and it is equal to mg.
Therefore, the minimum force is required is, f = 0.3 mg Newton
<u>Answer:</u>
The correct answer option is C. buzzer.
<u>Explanation:</u>
We know that Jeff's father needs to get a device from his workshop that converts electrical energy to sound energy.
So from the given options, buzzer is the best option Jeff's father can install in his house's security system.
An electric buzzer converts an electrical oscillating voltage into a sound output. In other words, the electrical pulses are converted into sound vibrations.
