Opposition for the current flow
Explanation:
- Resistance is defined as the ability pf the conductor to oppose the flow of electrons through it. It is usually represented in Ohm.
- Resistance is an important parameter in a circuit design and it should be properly designed.
- Resistance of a conductor depends upon the material nature, length of the conductor and area of cross section.
- In conductor, Resistance is low. It is due to that charges flow through the conductor freely.
Answer:
the final velocity of the cart is 30 m/s
Explanation:
Given;
initial velocity of the cart, u = 10 m/s
distance moved by the cart, d = 200 m
acceleration of the cart, a = 2.0 m/s²
The final velocity of the cart is calculated as;
v² = u² + 2ad
where;
v is the final velocity
v² = 10² + 2(2)(200)
v² = 900
v = √900
v = 30 m/s
Therefore, the final velocity of the cart is 30 m/s
Answer:
Because molecules are to small for us people to see with the bare eye, unless you use a telescope.
Explanation:
Question 9 is 100 N.
Question 10 is No, the bike's motion is not changing so it could be at rest or moving at a constant velocity.
Question 11 is Be doubled.
Question 12 is Ella is correct.
Hope i helped.
