A 20.5 kg ball moving at 38.5 m/s on a horizontal, frictionless surface runs into a light spring of force

tekilochka [14]

Answer:

7.68 m

Explanation:

Kinetic energy in ball = elastic energy in spring

KE = EE

½ mv² = ½ kx²

mv² = kx²

x = v √(m / k)

x = (38.5 m/s) √(20.5 kg / 515 N/m)

x = 7.68 m

In 2014, about how far in meters would you have to travel on the surface of the Earth from the North Magnetic Pole to the Geogra

pogonyaev

Answer:

267.07 km

Explanation:

We have given the radius of the earth = 6378.1 km

In 2014 the difference between the magnetic north pole and geographical north pole is 2.40°

2.40° $=2.40\times \frac{\pi }{180}=0.041866 radian$

We know that linear distance is given by $S=R\Theta =6378.1\times 0.041866=267.07km$

So we have to travel 267.07 km in going from magnetic north pole to geographic north pole

Can someone help me solve this its a simple series circuit

daser333 [38]

Answer:

See the explanation below.

Explanation:

Indeed this is a serial circuit, in order to calculate the different questions, we must calculate the current of the circuit. The total resistance of the circuit can be calculated by means of an algebraic summation.

Then using ohm's law,we can calculate the current.

Rt = 2 + 4 + 6 = 12 [ohm]

The current

I = V / Rt

I = 12 / 12

I = 1 [amp]

Therefore the voltage in each resistance will be:

V1 = 2 * 1 = 2 [V]

V2 = 4 * 1 = 4 [V]

V3 = 6 * 1 = 6 [V]

The total voltage will be:

V = V1 + V2 + V3 = 12 [V]

The power can be calculated by multiplying the voltage by the total current.

P = V * I

P = 12 * 1

P = 12 [W]

what is relative velocity in one dimension if va and vb are the velocities of two body a and b respectively then prove vab=va -v

motikmotik

Answer:

Relative velocity is nothing but the velocity of one body with respect to the velocity of some other body.

Explanation:

Relative velocity may be defined as the rate at which the change of separation takes place between any two object.The relative velocity of any object A w.r.t. another object B when they are in motion is nothing but the rate of change of their position from one another.

Now, let the velocity of object A be $v_A$

and velocity of object B is $v_B$

Therefore, relative velocity of a object A when compared to the velocity of object B is given by $v_{AB}=v_A - v_B$ .
