C. Seismic energy
This is energy that is released in earthquakes.
Answer:
False
Explanation:
False
If brakes fail then we should not run against any object or wall to slow down the speed instead we should use friction forces slow down the car and shift gear to neutral to cease any acceleration.
By driving zig-zag motion friction force on the tires may stop the car after some distance.
Do not try to shut off the engine as it will lock the steering mechanism any prove fatal.
Protons and neutrons are held together inside the nucleus.
Explanation:
The strongest force in the universe is the nuclear forces holding the neuclons together in an atom.
This force is referred to as the strong nuclear forces. It is by far stronger than electromagnetic forces.
Nuclear forces are stronger than chemical binding forces which is seen between two particles attracting one another via static electricity.
It stronger than the gravitational force experienced by two equal masses that falls to the ground at the same speed.

Explanation:
The given data is as follows.
mass = 227.8 kg, volume = 0.1189
It is known that formula for volume of a sphere is and density is as follows.
Density = ........ (1)
=
= 1915.895
Hence, putting the given values into equation (1) as follows.
Density =
1915.895 =
= 227.8
r = 0.305
Thus, we can conclude that radius of the sphere is 0.305 .
Answer:
The correct option is A
Explanation:
Firstly, it should be noted that the freezing point of a substance can be assumed to be melting point of that substance because a substance will normally change from liquid to solid (freezes) at the same point it changes from solid to liquid (melts). For example, water freezes at 0°C and also starts melting at 0°C.
Thus, the substance with the lowest melting point among the substances mentioned in the question is alcohol (ethanol) with the melting point of -114°C. Hence, <u>ethanol also has the lowest freezing point thereby freezing at the lowest temperature.</u>
