Answer:
1. Current is usually the flow of <u>electrons</u>.
Explanation:
The flow of charges through a wire or conductor is called electric current.
Pluto is the last planet discovered in our solar system.
Answer:
734.16 kg m/
Explanation:
The problem is asking for the Force of pushing off the ground.
- The formula of Force is: F = mass x acceleration
Given = <em>Mass</em>: 600 newtons (N)
<em>Acceleration</em>: 12 m/
We have to convert the mass into kg first. Remember that <u>1 kg is equal to 9.80665 newtons.</u>
Let x be the<em> mass in newtons</em>.
Let's convert:
x
=
= 61.18 kg
Phil's weight is 61.18 kg
Let's go back to finding the force.
F = m x a
F = 61.18 kg x 12 m/
F = 734.16 kg m/
Answer:
v = 3.27 m/s
Explanation:
KE = 1/2 mv^2
695 J = 1/2 (130kg)(v^2)
695 J / (1/2 x 130kg) = v^2
v^2 = square root of 10.69
v = 3.27 m/s
Answer:54 kj
Explanation:P1 = P2 = 1000 kPa
1Q2 = 84 kJ
1W2 = P1 (V2 – V1)
= 1000 (0.06 – 0.03) = 30 kJ
1Q2 = 1W2 + 1U2
U2 – U1= 1Q2 – 1W2 = 84 – 30 = 54 kJ
