A particle of charge and mass kg is released from rest in a region where there is a constant electric field of +668 N/C. What is the displacement of the particle after a time of?

Answers

Answer:

The displacement of the particle after a time of 3.64 × 10⁻² s = 0.366 m

Explanation:

Given q = 19.6 μC = 19.6 × 10^-6 C

m = mass of the charge = 2.37 × 10^-5 kg

E = 668 N/C

We first calculate the force on the charge

F = Electric field × Charge = Eq = 668 × 19.6 × 10⁻⁶ = 0.0131 N

Then, using Newton's law of motion's F = ma

We can obtain the acceleration of the particle

0.0131 = 2.37 × 10⁻⁵ × a

a = 0.0131/(2.37 × 10⁻⁵) = 552.4 m/s²

Then, using the equations of motion, we can obtain the displacement of the charge after t = 3.64 × 10⁻² = 0.0364 s

u = initial velocity = 0 m/s (since the particle was initially at rest)

t = 0.0364 s

a = 552.4 m/s²

d = displacement of the particle = ?

d = ut + at²/2

d = (0)(0.0364) + (552.4)(0.0364²)/2 = 0 + 0.366 = 0.366 m

An oil tanker, initially traveling west at 18 km/h is accelerated uniformly until it is traveling east at 21.6 km/h. The acceleration is 0.20 m/s2 towards the east. Compute the total displacement from the tanker’s initial position.Answer in meters.

Answers

Answer:

27.5 m

Explanation:

Given:

u = 18 km/h = 5 m/s

v = 21.6 km/h = 6 m/s

a = 0.20 m/s²

Find: s

v² = u² + 2as

(6 m/s)² = (5 m/s)² + 2 (0.20 m/s²) s

s = 27.5 m

Define circular motion and give some examples.

Answers

"Circular motion" is motion in a circular path.

-- Any point on the tire of a bicycle or a car that is moving.

-- Any point on the hour, minute, or seconds-hand of an 'analog' clock.

-- The ball in the roulette wheel before it comes to a stop.

-- Any point on the rim of the Wheel of Fortune before it stops.

-- Any point on any propeller of a windmill, when the wind is blowing.

MOTION OF THE BODY CIRCULAR PATH IS CALLED CIRCULAR MOTION

FEW IMP POINTS ABOUT IT :-

  1. ‌A tengential is always responsible for change in speed
  2. ‌If the Direction of acc and velocity is same then body's speed inc
  3. ‌If they r in oppsite direction then Body's speed dec .
  4. ‌If speed becomes constant then tangential acc become zero .
  5. ‌By the basis of tangial acc the circular motion is divided into two types uniform circular motion and non uniform circular motion

  1. ‌when object in a circular path in a constant speed or constant circular speed is called uniform circular motion.
  2. ‌In case of uniform circular motion acc tendial will be zero
  3. ‌In case of uniform circular motion acc centripetal will be equal to net acc.

Discuss the force that exists between the Earth and the moon by referring to the mass of each.

Answers

The word gravity is used to describe the gravitational pull (force) an object experiences on or near the surface of a planet or moon. The gravitational force is a force that attracts objects with mass towards each other. Any object with mass exerts a gravitational force on any other object with mass.
