Answer:
They attract or repel other charged objects without touching them.
Explanation:
My chemistry teacher always says like repels like opposite attracts.
Double pressure and you get the volume.At constant temp. volume =5L
P1V1=P2V2
100 times 2=200timesV2
V2=1000/200
V2=5.0l
Answer:
9000J
Explanation:
Given parameters:
Mass of the jet fighter = 5kg
Velocity = 60m/s
Unknown:
Kinetic energy of the jet fighter = ?
Solution:
The kinetic energy of a body is the energy due to motion of the body.
It is mathematically expressed as;
K.E =
m v²
m is the mass
v is the velocity
So;
K.E =
x 5 x 60² = 9000J
