1) when a Car Moves; its Wheels exhibit Both Rotational and Rectilinear Motion

2) When Earth rotates Around the sun it is executing Periodic motion through revolving around the sun; at the same time it is executing Rotatory motion by rotating on its own axis.

Hope it helps...

T Or F- True or False There three types of cloud's are .

AURORKA [14]

Answer:

There are three main cloud types.

The foundation consists of 10 major cloud types. In addition to cirrus, stratus, cumulus, and nimbus clouds, there are cirrostratus, cirrocumulus, altostratus, altocumulus, stratocumulus, nimbostratus, and cumulonimbus clouds. The following table places these cloud types into the four major cloud groups.

A coil has N turns enclosing an area of A. In a physics laboratory experiment, the coil is rotated during the time interval delt

zmey [24]

Answer:

a) Magnetic flux before the plane is rotated = (BA) Wb

b) Magnetic flux after the plane is rotated = 0 Wb

c) Magnitude of the average induced emf =

(NBA)/Δt

Explanation:

The magnetic flux is given as

Φ = BA cos θ

where B = magnetic field strength

A = Cross sectional Area of the loop enclosed

θ = the angle in the equation above is between the line normal to plane (NOT the plane itself!) and the magnetic field.

a) Given that the position of the plane of each turn is perpendicular to Earth's magnetic field before being rotated.

Before the plane is rotated, θ = 0°

Φ = BA cos θ = BA cos 0° = BA

b) Given that the position of the plane of each turn is parallel to Earth's magnetic field after being rotated.

After the plane is rotated, θ = 90°

Φ = BA cos θ = BA cos 90° = 0

c) According to the Faraday's law of electromagnetic induction,

E = - N (ΔΦ/Δt) (minus sign to indicate that the direction of the induced emf is opposite the direction of the change of magnetic flux)

ΔΦ = (final Φ) - (initial Φ) = (0 - BA) = - BA

E = - N (- BA)/Δt

E = (NBA)/Δt

Hope this Helps!!!

(a) Calculate the electric field strength near a 10.0 cm diameter conducting sphere that has 1.00 C of excess charge on it. (b)

Romashka-Z-Leto [24]

Electric field strength near the surface of sphere is given by

$E = \frac{kQ}{r^2}$

Now we have

Q = 1 C

R = 5 cm

now electric field is given by

$E = \frac{9*10^9 * 1}{0.05^2}$

$E = 3.6 * 10^{12} N/C$

Part B)

Since charge on the sphere is very large to electric field near its surface is too high. So this is reasonable result near it.

Part c)

As per our assumption the charge is uniformly distributed on the surface and there is no effect of surrounding charge or surrounding electric field.
