What is the distance traveled by an object that moves with an average speed of 6.0 meters per second for 8.0 seconds

Answers

Answer 1

Answer:

The distance traveled by the object is 48 m.

The given parameters;

average speed of the object, = 6 meters per second

time of motion of the object, t = 8 s

The distance traveled by the object is calculated as follows;

$s = ((v+ u)/(2) )* t$

where;

$(v+u)/(2)$ is the average speed of the object

Now, substitute the given values and solve for the distance traveled by the object;

$s = ((v+ u)/(2) )* t\n\n\s = 6 * 8\n\n\s = 48\ m$

Thus, the distance traveled by the object is 48 m.

Answer 2

Answer:

This is a Physics question where we need to figure out how many meters Cam can run per second. To figure this out we divide the distance by the change in time.

40/5.79 = 6.9 meters per second approximately.

At a certain elevation, the ________ , the air becomes saturated and water-vapor molecules ________.

Answers

At certain altitude, the temperature of air decrease, The air becomes saturated and water vapour molecules starts condensing.

As the altitude of air increase, the atmospheric pressure decrease due to which the temperature of the air decrease. The water molecules in the atmosphere start condensing, which saturate the air (that is air can no hold water molecules), due to which the water vapour molecules starts condensing and falls on the earth in the form of rain.

A ball is at rest at the top of a hill. It rolls down the hill. At the bottom of the hill the ball hits a wall and stops. Which energy changes occur? A) Gravitational potential energy, internal energy, kinetic energy B) Gravitational potential energy, kinetic energy, internal energy C) Kinetic energy, gravitational potential energy, internal energy D) Kinetic energy, internal energy, gravitational potential energy

Answers

Final answer:

The correct answer is C) Kinetic energy, gravitational potential energy, internal energy.

Explanation:

When the ball is at the top of the hill, it has gravitational potential energy because of its position. As it rolls down the hill, this potential energy is converted into kinetic energy, which is the energy of motion.

When the ball hits the wall at the bottom of the hill and stops, some of the kinetic energy is transformed into internal energy, which is the energy associated with the motion of particles within the ball.

A lamp can work on 50V mains taking 2 amps. What value of resistance must be connected in series with it, so that it can be operated from 200V mains giving the same power?

Answers

The resistance of the lamp is apparently 50V/2A = 25 ohms.

When the circuit is fed with more than 50V, we want to add
another resistor in series with the 25-ohm lamp so that the
current through the combination will be 2A.

In order for 200V to cause 2A of current, the total resistance
must be 200V/2A = 100 ohms.

The lamp provides 25 ohms, so we want to add another 75 ohms
in series with the lamp. Then the total resistance of the circuit is
(75 + 25) = 100 ohms, and the current is 200V/100 ohms = 2 Amps.

The power delivered by the 200V mains is (200V) x (2A) = 400 watts.

The lamp dissipates ( I² · R ) = (2² · 25 ohms) = 100 watts.

The extra resistor dissipates ( I² · R) = (2² · 75 ohms) = 300 watts.

Together, they add up to the 400 watts delivered by the mains.

CAUTION:
300 watts is an awful lot of power for a resistor to dissipate !
Those little striped jobbies can't do it.
It has to be a special 'power resistor'.
300 watts is even an unusually big power resistor.
If this story actually happened, it would be cheaper, easier,
and safer to get three more of the same kind of lamp, and
connect THOSE in series for 100 ohms. Then at least the
power would all be going to provide some light, and not just
wasted to heat the room with a big moose resistor that's too
hot to touch.
