A man travellers 10 km to the east 20 km to the north. Find distance moved displacement

Answers

Answer 1

Answer: $x^2=10^2+20^2\n x^2=100+400\n x^2=500\n x=√(500)=10\sqrt5 \approx22.36\hbox{ km}$

Suppose that at room temperature, a certain aluminum bar is 1.0000 m long. The bar gets longer when its temperature is raised. The length l of the bar obeys the following relation: l=1.0000+2.4×10−5T, where T is the number of degrees Celsius above room temperature. What is the change of the bar's length if the temperature is raised to 14.1 ∘C above room temperature?

Answers

Answer:

0.00034 m

Explanation:

Since the length of the aluminium bar, L is given by , L = 1.0000 + 2.4 × 10⁻⁵T and T = 14.1°C, we substitute the value of T into L. So, we have L = 1.0000 + 2.4 × 10⁻⁵ × 14.1°C = 1.0000 + 0.0003384 = 1.0003384 m. The change in length is thus 1.0003384 - 1.0000 = 0.0003384 m ≅ 0.00034 m

A device that uses electricity and magnetism to create motion is called a _________motor,magnet,generator . In a reverse process, a device that uses motion and magnetism can be used to create ________ light,electromagnetism,electricity

Answers

Answer:

1. motor

2. electricity

Explanation:

A motor uses electromagnetism or electricity and magnetism to create motion. A motor converts electric energy into mechanical energy.

On the other hand, the reverse process of using motion and magnetism will create electricty. It will convert the mechanical energy to electrical energy. And the machine that does it is called a generator.

A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".

In short, 1st Blank = Motor
2nd Blank = Electromagnetism

One component of a magnetic field has a magnitude of 0.0404 T and points along the x axis while the other component has a magnitude of 0.0739 T and points along the y axis A particle carrying a charge of 2.80 10 5 C is moving along the z axis at a speed of 4.46 103 m s a Find the magnitude of the net magnetic force that acts on the particle b Determine the angle that the net force makes with respect to the x axis

Answers

Answer:

as we find the resultant of the magnetic field we get in the xy plane. Just perpendicular to this plane i.e. along z-axis the charge is moving. Hence the force acting on the charge will also be in the xy plane.

Net field = ./(0.078^2 +0.070^2) = 0.105 T

Angle with x axis is arc tan 0.070/0.072 = 44.2 deg

So the force acting on the moving charge is got by Bqv

0.105*5.5*10^-5 * 6*10^3 = 0.03465 N

So the angle inclined by this force with x axis will be 90+44.2 = 134.2
