Answer:
C
Explanation:
The kinetic energy of a body is the energy due to the motion of a body. It is mathematically given as;
Kinetic energy = 
m v²
m is the mass of the body
v is the velocity
Now, let us find the K.E from the given choices;
Option C will have the greatest kinetic energy;
mass = 0.14kg , v = 40m/s
Kinetic energy = x 0.14 x 40² = 112J
Answer:
The correct answer will be "18.25 g".
Explanation:
The given values are:
Specific heat,
C = 0.45 J/g･°C
Heat involved,
q = 801 J
Temperature,
ΔT = 120.0°C-22.5°C
= 97.5°C
As we know,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
C. If the banks of the river are eroding, then the river will be wider.
