Calculate the velocity of a 1650 kilogram satellite.

Answers

Answer 1

Answer:
There's not enough information given to do that calculation.

-- The question doesn't specify whether the satellite is on the
shelf in the Vehicle Assembly Building before being installed
onto the booster, or inside the nose-cone as the rocket is slowly
being rolled to the launch-pad, or on its ascent to orbit after launch,
or in orbit. Its velocity in each of these situations is different.

-- The question reveals only the satellite's mass, but the answer
doesn't depend on that number. The satellite's velocity depends
on the speed of the truck or the rocket carrying it, or the size of
the orbit it's in. The question doesn't give any of these.

==> In particular, the size of a satellite's orbit, or its speed in that
orbit, DO NOT depend on its mass.

For example:
There are hundreds of TV satellites ... the ones that match the
Earth's rotation and appear motionless in the sky. They have
many different sizes, shapes, and masses, but they're all in the
same geostationary orbit, 22,000 miles above the equator, and
they all have the same average orbital velocity, zero displacement
per (23 hours 56 minutes 4 seconds).

When heating a substance, a phase change will start to occur when the kinetic energy of the particles is _____________ the attractive forces between the particles. Question 8 options: A. great enough to combine
B. low enough to combine
C. low enough to overcome
D. equal to
E. great enough to overcome

Answers

Answer: E. great enough to overcome.

Explanation: The three phases of the substances are solid, liquid and gas.

When a substance is heated, that is the molecules gain kinetic energy as kinetic energy is directly proportional to temperature.

The phase change will take place only when kinetic energy will be greater than the inter molecular forces as the molecules have to move in more random motion.

For example: Solid with high inter molecular forces are heated to convert it into liquid state only when kinetic energy will overcome the inter molecular forces of attraction.

Your answer is great enough to overcome :)

A baseball on a T-ball stand has no momentum until it is hit with a bat. When Tyler swings the bat, it has a momentum of 12 kg m/s. After the bat hits the ball, the ball has a momentum of 8 kg m/s. What is the momentum of the bat AFTER it hits the ball

Answers

Answer:

4 kg m/s

Explanation:

According to the Law of Conservation of Momentum, the total momentum must be the same before and after a collision. The total momentum before the bat hit the ball was 12 kg m/s. After the collision, the ball has a momentum of 8 kg m/s. Therefore, the bat must have a momentum of 4 kg m/s.

positive direction : bat swing

total momentum before = after
12(bat) + 0(ball) = 8(ball) + bat-after

bat-after is positive then direction is the same

Explanation:

Deimos completes one (circular) orbit of Mars in 1.26 days. The distance from Mars to Deimos is 2.35×107m. What is the centripetal acceleration of Deimos?

Answers

Answer:

The centripetal acceleration of Deimos is $0.077m/s^(2)$ .

Explanation:

The centripetal acceleration is defined as:

$a = (v^(2))/(r)$ (1)

Where v is the velocity of Deimos and r is the orbital distance.

Notice that is necessary to determine the velocity first.

The speed of the Deimos can be found by means of the Universal law of gravity:

$F = G(M \cdot m)/(r^(2))$ (2)

Then, replacing Newton's second law in equation 2 it is gotten:

$m\cdot a = G(M \cdot m)/(r^(2))$ (3)

However, a is the centripetal acceleration since Deimos almost describes a circular motion around Mars:

$a = (v^(2))/(r)$ (4)

Replacing equation 4 in equation 3 it is gotten:

$m(v^(2))/(r) = G(M \cdot m)/(r^(2))$

$m \cdot v^(2) = G (M \cdot m)/(r^(2))r$

$m \cdot v^(2) = G (M \cdot m)/(r)$

$v^(2) = G (M \cdot m)/(rm)$

$v^(2) = G (M)/(r)$

$v = \sqrt{(G M)/(r)}$ (5)

Where v is the orbital speed, G is the gravitational constant, M is the mass of Mars, and r is the orbital radius.

$v = \sqrt{((6.67x10^(-11)N.m^(2)/kg^(2))(6.39x10^(23)kg))/(2.35x10^(7)m)}$

$v = 1346m/s$

Finally, equation 4 can be used:

$a = ((1346m/s)^(2))/(2.35x10^(7)m)$

$a = 0.077m/s^(2)$

Hence, the centripetal acceleration of Deimos is $0.077m/s^(2)$ .

Final answer:

The centripetal acceleration of Deimos, one of Mars' moon, can be calculated using its orbital period and distance from Mars. Convert the time units to seconds and use the formulas for velocity and centripetal acceleration to get an answer of approximately 7.84x10^-5 m/s^2.

Explanation:

To find the centripetal acceleration of Deimos, we can use the formula for centripetal acceleration, which is a =v^2/r , where v is the velocity and r is the radius (distance from Mars to Deimos). The velocity can be found using the formula v = 2πr/T, where T is the period (time for one complete orbit).

First, convert the days into seconds because the SI unit of time in physics is second. So, 1.26 days = 1.26 * 24 * 60 * 60 = 108864 seconds.

Then, calculate the velocity: v = 2 * π * 2.35x10^7m / 108864s = 1.36 km/s.

Finally, substitute v and r into the centripetal acceleration formula: a = (1.36x10^3m/s)^2 / 2.35x10^7m = 7.84x10^-5 m/s^2.

The centripetal acceleration of Deimos is approximately 7.84x10^-5 m/s^2.
