The solution for this is:
Power = Energy transferred / Time taken
Energy Transferred in one second ( Power) = mgh/s
= (1.2x10^6)(9.8)(50) = 588000000 J/s
Power = 588000000 W
Or
Power is work done / time
Work done in one second = [ rate of fall of mass]
gh = 1.2* *9.81*50 x 10^6 J/s
= 5.886e+8 W
Electrons carry a negative charge.
Answer:
C. Electric energy
Explanation:
A generator is designed to convert chemical energy to mechanical energy and them electrical energy.
- It is an alternate source of electricity for most homes and industrial establishments.
- The source of energy for the generator is a fuel usually fossil fuels.
- This energy source is ignited and it produces heat energy which drives the motion of the pistons in the set.
- As the piston moves, an magnetic field is cut through by a conducting wire.
- This inducts the production of currents.
Answer:
a=1.03 m/s²
Explanation:
given required
dist=22.1 cm a=?
m1=2.1 kg
m2=1.56 kg
m3=1.93 kg
g=9.8 m/s²
solution
there are three forces on this system so we can solve by using newton's second law as follows
t1,t2,and weight of are the only forces acted on the system,
if we take the system on the left mass m3
-m3a=t2-m3g
-1.93 kg×a=t2-1.93 kg×9.8 m/s²
-1.93 kg×a=t2-18.91 N................................ eq 1
take at the right mass m2
m2a=t2-m2×g
1.56 kg×a=t2-1.56 kg×9.8 m/s²
1.56 kg×a=t2-15.288 N...................................2
add the two equations simultaneously and then solve for a,
-1×(-1.93 kg×a=t2-18.91 N) multiply by -1 the first and add the two equations
1.56 kg×a=t2-15.288 N
3.49 kg×a=3.622 N
a=1.03 m/s²
