Answer:
Explanation: Here we have given a direct equation . There for no need to worry .
P = I²×R
P = (12)² ×100
P = 14400W = 14.4 kW
For second one
P = I² ×R
200 = I²×150
I = √200/150
I = 1.15 A
Answer:
e. Only(a) and (b) above are correct
Explanation:
Impulse
= Fx t = m ( v-u )
v-u = change in velocity
F x t = mass x change in velocity
change in velocity = F t / mass
=a t
change in velocity ∝ t ( time ) , if a is constant
dv = a_avg dt
∫dv = a_avg ∫dt
v-u = a_avg t
change in velocity ∝ t ( time )
So both (a) and (b) are correct.
Hello There!
Great Question You Asked.
I Will Provide A Number Of Steps To Below To Show You Measures of Being Safe
Number 1.
Find shelter immediately. If you find yourself caught in a lightning storm, the key to minimizing danger is to get inside a protective structure. While most people seek shelter if lightning appears to be near, people commonly wait too long to seek shelter. If you can detect lightning, it may be close enough to strike you so always make sure you are safe.
Number 2.
Try to stay away from windows because windows provide a direct path for lightning.
Number 3.
Don’t touch anything metal or electrical.
Answer:
In astrophysics and nuclear physics, nuclear pasta is a theoretical type of degenerate matter that is postulated to exist within the crusts of neutron stars. If it does in fact exist, nuclear pasta is the strongest material in the universe.
Explanation:
Answer:
D. A 10 kg rock at 15°C
Explanation:
Thermal energy is heat energy, meaning that the hotter rocks will have more energy.
The heavier/larger rocks can store more energy.
So if we combine the largest two variables, we get a 10kg rock at 15°C.
