• What happens to similar charged particles and differently charged particles

Physics
1 answer:
mixas84 [53]3 years ago
8 0

Answer:

Like charges repel

Different charges attract

Explanation:

When particles of similar charges are brought together, they repel each other and increase the distance of separation. Repulsion occurs because both two electrons have negative electrical charge forcing their lines of force to repel. However, when particles of opposite charges are brought nearer to each other, they attract each other and reduce the distance of separation.

A train travels 55 kilometers in 2 hours, and then 52 kilometers in 5 hours. What is its average speed?
bulgar [2K]

The formula for working out speed is distance ÷ time.

55 km ÷ 2 hours = 27.5 km/h (average speed for first part of journey)

52km ÷ 5 hours = 10.4 km/h (average speed for second part of journey)

(27.5 + 10.4) ÷ 2 = 18.95 km/h (average speed throughout the journey)

An object of inertia 0.5kg is hung from a spring, and causes it to extend 5cm. In an elevator accelerating downward at 2 m/s^2 ,
Sidana [21]

Answer:3.98cm

Explanation:

given data

mass of object\left ( m\right )=0.5kg

intial extension=5 cm

elevator acceleration=2 m/s^2

From FBD of intial position

Kx=mg

K=\frac{0.5\times 9.81}{0.05}

k=98.1 N/m

From FBD of second situation

mg-kx_0=ma

kx_0=m(g-a)

x_0=\frac{0.5(9.81-2)}{98.1}

x_0=3.98cm
