The higher mass of a particle means it’ll be harder to move, slowing it down and the faster the particle is moving the higher the kinetic energy because there is more movement and pressure within the object with the energy
Answer:
Explanation:
Magnetic field due to a solenoid
B = μ₀ nI where n is no of turns per unit length and I is current
for outer layer of turns
B = μ₀ x (250 / .3) x 3
= 4π x 10⁻⁷ x (250 / .3) x 3
= 3.14 x 10⁻³ T
for inner layer of turns
B = μ₀ x (300 / .3) x 3
= 4π x 10⁻⁷ x (300 / .3) x 3
= 3.77 x 10⁻³ T
Total magnetic field
= (3.14 + 3.77 ) x 10⁻³ T
= 6.91 x 10⁻³ T .
Answer the term solenoid refers to a long, thin loop of wire, often wrapped around a metallic core, which produces a magnetic field when an electric current is passed through it. Solenoids are important because they can create controlled magnetic fields and can be used as electromagnets

Answer: Arrow B
Explanation:
Arrow B best best represents the path the ball follows after the string breaks.
This is because the described situation is related to <u>uniform circular motion</u>, in which the tangential velocity is the linear velocity vector that is <u>always tangent to the trajectory</u> and is the distance traveled by the ball in its circular motion in a period of time.
Hence, if this circular motion suddenly stops, the ball will fly in a direction that is tangent to that circle.
Answer:
f = -60 cm, this means tha the focal point is on the same side as the side where the object is located.
Explanation:
let u be the distance from the lens to the object and u = -35 cm, v be the distance from the lens to the image and m is the magnification and m = -v/u and f is the focal point.
