When it has been proven by science to be true.
The option “The sum emitting light energy” does not describe the conversion of potential energy to kinetic energy.
Answer: Option A
<u>Explanation:
</u>
The potential energy, the object's energy at rest while the kinetic energy is the energy the object in motion. So among the options given, a rocket leaving the Earth's atmosphere consists of conversion of potential energy as the thrusting force to kinetic energy of the movement of the rocket to space.
Similarly the stretching of rubber band is a form of elastic potential energy and when it is released, the band will vibrate which will be the converted kinetic energy.
Also, the avalanche is the falling of ice berg which were once in rest, so the potential energy of the ice berg will get converted to kinetic energy during avalanche.
The option that is the sun emitting light does not convert potential to kinetic energy, instead it converts potential to light energy.
The amount of matter contained by an object is called mass.
A. mass
<u>Explanation:</u>
Mass is fundamentally a property of any physical amount and it is additionally the estimation of the resistance from the acceleration when force is applied on an object. The mass equals the quality of the gravitational force on a body.
Mass, in material science, the quantitative proportion of idleness, a crucial property of all matter. The greater the mass of a body, the littler the change created by an applied power. The mass of an object can be portrayed by its capacity to oppose a given power (we once in a while call this a body's inertial mass and subsequently mass is personally connected with the idea of inertia).
This is a straightforward result of Newton's second law where the power F, on a body is equivalent to the mass m, times the speeding up an, it encounters, ie:
F=ma or m=F/a
Mass of an object can not be zero but weight can be zero. The mass and weight of an object are different things.
Answer:
3.025 revolutions
Explanation:
To solve this question firstly we need to calculate the time t
Given the angular velocity and the angular acceleration
The time t = angular velocity/angular acceleration
Converting 50rpm to rad/s
= 50 × 2π /60
=1.67 rad/s
t = 1.67/0.46
t =3.63s
The wheel makes 50 revolutions in one minute
Therefore in 3.63s, it will make
3.63 × 50/60
= 181.5/60
=3.025 revolutions
Approximately 3 revolutions
Answer:
3×10^-12 C
Explanation:
The total of the three charges is ...
(-3 +8 +4)×10^-12 C = 9×10^-12 C
Assuming the charge is equally distributed between the balls when they are brought in contact, the charge on each ball will be ...
(9/3)×10^-12 C = 3×10^-12 C
