Answer : Total electrical energy is 36000 J.
Explanation :
It is given that,
Power of electric toaster, P = 1200 Watts
Voltage, V = 120 Volts
Time, t = 30 s
Electric energy is defined as the product of the power and the time taken.
Total electrical energy used to operate the toaster for 30 seconds is 36000 J.
Answer:
9,000 N.
Explanation:
Workdone can be defined as the ability to do work. It is also the product of the force and the distance it is being moved.
Mathematically,
W = F * d
= 180,000/2
= 90,000 N.
Weight of the 10 cars = 90,000 N.
Weight of a car = 90000/10
= 9,000N.
The light reactions could be viewed as analogous to a hydroelectric dam. In that case, the wall of the dam that holds back the water would be analogous to the thylakoid membrane.
Thylakoid membrane is present in cyanobacteria and chloroplasts of plants. It plays a crucial role in photosynthesis and photosystem II reactions.
In general, these are the regions where light-dependent reactions take place. The thylakoid membrane is a lipid-bound membrane that maintains potential difference and also controls the flow of liquids across the membrane during light reactions.
In the provided case, we can see that the wall of the dam holds back the water, similarly, in light-dependent reactions, thylakoid membranes control the liquid flow and also regulate the potential gradient across the membrane and also allow the selective proteins to pass through.

Answer:
This is an example of Inelastic colission
Explanation:
Step one:
given:
mass of moose m1 = 620 kg
mass of train m2= 10,000kg
Initial velocity of moose u1= 0 m/s
Initial velocity of train v1 = 10m/s
combined velocity of the system is given as v
Applying the conservation of momentum equation we have
m1u1+ m2u1= (m1+m2)V
substitutting we have
620*0+10000*10= (620+10000)V
100000= 10620V
divide both sides by 10620
V = 100000/10620
V=9.41m/s
The velocity of the moose after impact is 9.41m/s
Mass of object/source
Gravity
Fg=mg
