Answer:
The linear charge density is 5.19 X 10⁻⁶ C/m
Explanation:
The potential difference between two cylinders, is given as
V = (λ/2πε)ln(b/a)
where;
λ is the line charge density on the power line.
b is the distance between the power line = 1 m
a is the radius of the wire = 1.5 cm = 0.015 m
ε is the permittivity of free space = 8.9 X 10⁻¹² C
V*2πε = λ* ln(b/a)
3900 *(2π*8.9 x10⁻¹²)= λ *ln(1/0.015)
2.1812 X 10⁻⁷ = 4.1997* λ
λ = 5.19 X 10⁻⁶ C/m
Therefore, the linear charge density is 5.19 X 10⁻⁶ C/m
Answer: 45000kgm/s
Explanation:
Given that:
Mass of speed boat = 1500 kg
Velocity of speedboat = 30 m/s
Speed boats Momentum = ?
The Speed boat momentum is the product of its mass and the velocity by which it moves. Momentum is a vector quantity and measured in kgm/s
i.e Momentum = mass x velocity
= 1500 kg x 30 m/s
= 45000kgm/s
Thus, the speed boats momentum is 45000kgm/s
Answer:
hypothesis: Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch. They will measure the height of the rocket launch in meters
Explanation:
Answer:
Explanation:
Speed= distance/time
Or time = distance/speed
According to your question
Speed=15m/s
and. Distance=1.2km. ,we must change kilometer in meter because given speed is in m/s
D= 1.2km = 1.2×1000m =1200meter
Time = distance/ speed
1200/15 =80second
Or. 1min and 20 sec will be your answer.
Answer:
D. momentum
Explanation:
Momentum is the product of velocity and mass which is the two variables the paragraph talked about.
