Answer:

If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave. With regard to transverse waves in matter, the displacement of the medium is perpendicular to the direction of propagation of the wave.

An oil bath maintained at 50.5°C loses heat to its surroundings at the rate of 4.68 kJ/min. Its temperature is maintained by an

NISA [10]

Answer:

The fraction of the time is 38.67%.

Explanation:

Given that,

Energy = 4.68 KJ

Resistance = 60

Voltage =110 V

If the rate of heat energy supplied by the coil to the oil bath = Q

$Q=4.68\ kJ/min$

We need to calculate the power released by the resistor at voltage

$P=\dfrac{V^2}{R}$

Put the value into the formula

$P=\dfrac{110^2}{60}$

$P=201.7\ W$

$P=12.102\ KJ/min$

We need to calculate the fraction of the time

$T=\dfrac{Q}{P}$

Put the value into the formula

$T=\dfrac{4.68}{12.102}$

$T=0.3867$

The percentage of time is

$T = 38.67\%$

Hence, The fraction of the time is 38.67%.

What is the speed of an object at rest

sammy [17]

The speed of an object is measured by calculating the distance it travels per unit time.
The formula in Physics for calculating speed is = distance/ time.

Since an object at rest is not covering any distance, the speed is always assumed to be 0 m/s.

What is the force of gravitational attraction between an object with a mass of 100 kg and another object that has a mass of 300

Leokris [45]

Answer:

5 x 10⁻⁷N

Explanation:

Given parameters:

Mass of object 1 = 100kg

Mass of object 2 = 300kg

Distance = 2m

Unknown:

Force of gravitational attraction between the objects = ?

Solution:

Newton's law of universal gravitation states that the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

From Newton's law of universal gravitation we derive an expression:

Fg = $\frac{Gm_{1} m_{2} }{r^{2} }$

G is the universal gravitation constant = 6.67 x 10⁻¹¹

m is the mass

r is the distance between the bodies

Now insert the parameters and solve;

Fg = 6.67 x 10⁻¹¹ x $\frac{100 x 300}{2^{2} }$ = 5 x 10⁻⁷N

5. How much power is dissipated when 0.2 ampere of current flows through a 100-ohm resistor ?

swat32

Answer:

P=I*I*R

Where P is power

I is current

R is Resistance

P=2*2*100

P=400W

Explanation:

Power is the rate of doing work.

From the Ohm’s law V=IR

Power=I*I*R
