Answer:

Resistance, R = 60 Ohms

Explanation:

Given the following data;

For the first heater;

Voltage, V = 120 V

Resistance, R = 15 Ohms

For the second heater;

Voltage, V = 240 V

To find the resistance in the second heater;

First of all, we would determine the power rating of the heaters using the formula below;

Power = voltage²/resistance

Power = 120²/15

Power = 14400/15

Power = 960 Watts

Next, we find the resistance in the second heater;

Power = V²/R

960 = 240²/R

Cross-multiplying, we have;

960R = 57600

R = 57600/960

R = 60 Ohms

What is the product of an object’s mass and velocity? momentum net force kinetic energy
kaheart [24]

<u>Answer:</u>

The correct answer option is momentum.

<u>Explanation:</u>

Momentum is the product of an object's mass and velocity.

It is a term which describes the relationship between the mass of an object and the velocity of an object.

Momentum can be represented in the form of an equation as:

P = mv

where P is the momentum,

m is the mass of the object; and v is the velocity of that object.

Sound waves with a constant frequency of 250 hertz are traveling through air at stp. what is the wavelength of the sound waves
Deffense [45]

Answer:

wave length is 1.2m

Explanation:

since formula of wave length is v/f

v(speed of sound in air at stp is 300ms^-1)

f(frequency 250hertz)

then wave length is 300÷250 which give 1.2m

As part of an exercise program, a woman walks south at a speed of 2.00 m/s for 60.0 minutes. She then turns around and walks nor
Anastaziya [24]

Answer:

Option A

Solution:

As per the question:

The distance covered by the woman in the North direction, d = 3000 m

Time taken to travel in North direction, t = 25.0 min = 1500 s

Velocity of woman in the south direction, v = 2.00 m/s

Time taken in the south direction, t' = 60.0 min = 3600 s

Now,

The distance covered in the south direction, d' = vt' = 2.00\times 3600 = 7200\ m

Now, the total displacement is given by:

D = d' - d = 7200 - 3000 = 4200 m in South

(a) Average velocity of the woman in the whole journey is given by:

v_{avg} = \frac{Total\ displacement}{Total\ time} = \frac{4200}{t + t'}

v_{avg} = \frac{4200}{1500 + 3600} = 0.8235\ m/s ≈ 0.824 m/s South
