<span>Question: How much power does an electric device use if the current is 36.0 amps and the resistance is 3.9 ohms? </span>
How?:
Equation: P = I^2 R
Meanings:
P = Power in Watts
I = Current in Ampere
R = Resistance in ohms.
Plugged in: P = 36^2<span> x 3.9 = 5054.4
Answer: P= </span>5100 watts.
HOPE THIS HELPS! ^_^

You start by writing down your parameters;
u=60m/s
v=0
t=8s
So acceleration(a)=v-u/t
=0-60/8
=-60/8
=-7.5m/s
To the nearest hundredth will be
-7.5*100
=-750m/s
Answer:
2 miles
Explanation:
Jimmy walked forward 3 miles east (to the right)
Then, he backtracked and walked 1 mile west (to the left)
This can be written as:
3 - 1 = ?
3 - 1 = 2
Therefore, Jimmy traveled a total of 2 miles.
Answer:
protons+neutrons= mass number, so if the mass number is 13 and protons are 6 its 13-6=7 neutrons
Explanation:
mass number: the sum of the number of protons and
neutrons in an atom
this is key as it explains that protons+neutrons= mass number, so if the mass number is 13 and protons are 6 its 13-6=7 neutrons
