Physics
1 answer:
s2008m [1.1K]2 years ago
7 0

Answer:

See below ~

Explanation:

Part (a) :

We can say a body is in uniform acceleration if the acceleration of the object remains constant with respect to time throughout its motion.

Part (b) :

We can say a body is non-uniform acceleration if the acceleration of the body varies with respect to time throughout its motion.

A charged particle of mass 6.00 mg moves with a speed of 4.00 km/s in a direction that makes an angle of 37o above the positive
AysviL [449]

Answer:

Explanation:

mass of charged particle m = 6 x 10⁻³ kg .

speed of particle   v  = 4 x 10³ m /s

speed of particle perpendicular to magnetic field = v sin37

= 4 x 10³ sin37

= 2.41 x 10³ m / s

Force on charged particle

= B q v , B is magnetic field , q is charge on particle and v is velocity perpendicular to B

Force = ma

= 6 x 10⁻³ x 8

= 48 x 10⁻³

Force = Bqv

48 x 10⁻³ = 5 x 10⁻³ q x  2.41 x 10³

q = 48 x 10⁻³  / (5 x 2.41)

= 3.98 x 10⁻³C.

Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons. This is because during summer or winter, one part of the planet is more directly exposed to the rays of the Sun than the other, and this exposure alternates as the Earth revolves in its orbit.

A rocket ship has several engines and thrusters. While the Solid Rocket Booster (SRB) and main engines only work together during
Alexeev081 [22]

The acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

The given parameters;

  • <em>initial velocity of the engine, u = 1341 m/s</em>
  • <em>final velocity of the engine, v = 7600 m/s</em>
  • <em>time of motion, t = 2 minutes = 2 x 60 s = 120 s</em>

The acceleration of the SRB and main engine is calculated as follows;

a = \frac{\Delta v}{\Delta t } \\\\a = \frac{7600 - 1341}{2 \times 60  s} \\\\a = 52.16 \ m/s^2

Thus, the acceleration of the SRB and main engine during the first 2.0 minutes of flight is 52.16 m/s².

A 10.0-cm-long solenoid of diameter 0.400 cm is wound uniformly with 800 turns. A second coil with 50 turns is wound around the
levacccp [35]

Answer:

M = 6.32 x 10⁻⁶ H

Explanation:

given,

Length of solenoid = 10 cm = 0.1 m

diameter = 0.40 cm

radius = 0.2 cm = 0.002

number of turns, N₁ = 800

                            N₂ = 50

mutual inductance will be equal to  

     M = \dfrac{\mu_0N_1N_2A}{l}

     M = \dfrac{4\pi \times 10^{-7}\times 800\times 50 \times \pi \times (0.002)^2}{0.01}

           M = 6.32 x 10⁻⁶ H

hence, mutual inductance of the combination of two coil is equal to  M = 6.32 x 10⁻⁶ H
