Answer:
No C. process of investigation that does not resemble science, but follows scientific methods.
- Mass=5+0.25=5.25kg
- Force=10N
According to Newton's second law
- F=ma
- a=F/m
- a=10/5.25
- a=1.9m/s²
P= mv
p=(.5)(20)
p=10 kg/ms
Answer:B
Explanation:
Given
First motor has three times as much as power as another
Let the power of smaller motor be P
Therefore bigger motor has power 3 P
and we know that energy 
Larger motor 
Smaller motor 
Therefore smaller motor will do same work if it takes three times the time taken by Larger motor
Answer:
- 1100 J heat flows out
Explanation:
dW = - 1600 J (as work is done on the gas)
dU = 500 J
dQ = ?
According to the first law of thermodynamics
dQ = dU + dW
dQ = 500 - 1600
dQ = - 1100 J
As heat is negative so it flows out.
