<u>Answer:</u>
The correct answer option is C. Kinetic energy from vibration.
<u>Explanation:</u>
The energy of the random motion of the particles of an object is referred to as the internal energy of that object (substance). So the type of energy that makes up most of the internal energy of a solid substance is kinetic energy from vibration.
Internal energy is related to the temperature. When heat is supplied to an object, the molecules vibrate and energy of these molecules increases.
Answer:
The distance is 0.9681 m.
Explanation:
Given that,
Length = 0.95 m
Mass of block = 7.9 kg
Stretches spring length = 1.06 m
another mass = 1.3 kg
Magnitude of restoring force acting in the spring equal to the magnitude of applied force
We need to calculate the spring constant
Using Hook's law,
Put the value into the formula
Put the value into the formula
We need to calculate the distance
Using formula of spring constant
Put the value into the formula
We need to calculate the total distance
Using formula of distance
Hence, The distance is 0.9681 m.
Momentum can be defined as a matter or mass in motion
Answer:
the speed of the car moving after accelerating for 56 m is 20 m/s
Explanation:
The computation is shown below:
As we know that
Vf^2 = Vi^2 + 2ad
= ( 8m/s )^2 + 2 ( 3m/s2 ) ( 56m)
= 400 m2/s2
Vf = 20 m/s
Hence, the speed of the car moving after accelerating for 56 m is 20 m/s
