Answer:
time = 8.3333 minutes.
Explanation:
distance between earth and sun = 1.5 * 
speed of light = 3* 
convert the distance unit from km to m so we can have uniform units.
distance between earth and sun = 1.5 *
m
distance between earth and sun = 1.5 *
m
speed = distance /time
time = distance / speed
time = 

time =500 sec
time = 500/60 minutes
time = 8.3333 minutes.
1 meter = 1e9 nm
To get meters, divide nanometers by 1e9: 9.95nm / 1x10^9 = 9.95x10^-9 meters
Answer: 9.95e-9 meters
Answer:
They're going to increase the total resistance as 
Explanation:
If the resistors are in parallel, the potential difference is the same for each resistor. But the total current is the sum of the currents that pass through each of the resistors. Then

but
for 
so

Answer:
J = 1800 kg-m/s
Explanation:
Given that,
Mass of a boy, m = 150 kg
Initial velocity of a boy, u = 12 m/s
Finally, it stops, v = 0
We need to find the impulse is required to produce this change in momentum. We know that impulse is equal to the change in momentum. So,

So, the impulse is equal to 1800 kg-m/s
