Answer:
Rate of change of specific energy will be
Explanation:
We have given mass of the motor oil m = 2.8 kg
Heat is transferred to the oil at a rate Q = 1 W
Power supply by stemming device
Applying first law to the device
Rate of change of specific energy will be
The energy released from glucose during this reaction is used and also wasted. Some of the energy is used as work while some amounts are used in other processes or stored for transfer to other organisms. Also, some of the energy is wasted in the form of heat.
Answer:
Total mass of combination = 2+3+5 = 10kg.
Acceleration produced = 2m/s^2
hence force =( total mass × acceleration)= (2×10)= 20 N.
Net force on 3kg block = acceleration × mass = (2 × 2 )= 4 N
applied force on 2 kg block = 20N
Force between 2 kg and 3 kg block = (20-4) = 16N. ans
Net force on 3 kg block = 3 × 2 =6N.
Applied force on 3 kg block due to 2 kg block = 16N.
hence, force between 3 kg and 5 kg block = (16-6) = 10N .
answers:-
(a) 20 N
(b) 16N
(c) 10 N
The highest point of a wave is called the crest. Among the choices, the correct answer is C. The height of the wave can be determined using the crest and the trough. The trough is the lowest point of a wave. The wavelength is the distance between two crests of a wave.
Answer:
Laws are created based on repeated experimentation.
Laws are based on observations.
Laws explain observations.
Explanation:
The complete question is..
Which statements correctly describe laws? Check all that apply.
-Laws are created based on repeated experimentation.
-Laws are based on observations.
-Laws explain observations.
-Laws are factual statements.
-Laws can be changed or replaced
Laws are based on the results of repeated experimentation, and observation, and they describe or predict some phenomenon in nature. Laws can't be said to be factual, as they might be seen to be constrained, or restricted and might need to be extended by future observations. Established laws explain observations, and laws cannot be changed or replaced, but can be extended, to predict future observations.
