Which planet has an enormous storm called the Great Red Spot swirling in its atmosphere?a. Jupiter
b. Saturn
c. Uranus
d. Neptune

Answers

Answer 1

Answer:

Answer:

a. Jupiter

Explanation:

The Great Red Spot is the largest anticyclonic vortex in the solar system. It is a great whirlpool that could exist for more than 300 years, since it is believed that observations in the 17th century are from the same storm, it is characterized by winds on its periphery of up to 400. $(km)/(h)$

Answer 2

Answer: Jupiter has an enormous storm called the Great red Spot swirling in its atmosphere.

answer: a. Jupiter

When a 191 N bag of nails hangs motionlessfrom a single vertical strand of rope, how
much tension is exerted in the strand?
Answer in units of N.

Answers

At the place where the rope meets the bag, the upward force
of the rope must be exactly the same as the downward force of
the load of nails. If the net force at that point were not zero, then
that point would be accelerating either upward or downward. So
the upward force of the rope at that point is 191 N.

I can't tell you about the tension higher up in the rope. If the rope
itself has any mass, then points higher up must support not only
the bag of nails but also the weight of the section of rope that is
below the point.

If the rope has no mass, then the tension is 191 N everywhere along it.

C.
Kinetic energy, temperature, and thermal energy decrease.

D.
Kinetic energy and temperature decrease; thermal energy increases.

Answers

When vibrational motion in an object increases, the statement that is true is that the kinetic energy temperature and thermal energy increases. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer comes to your help.

Describe all the forces acting on an elevator as it moves from rest upward and stops at its floor.

Answers

The force which acts on the elevator while it starts its motion are described as follows :

1. The elevator when starts from rest, moves in a direction opposite to the gravity, hence there is an upward force which acts on the elevator. It is more than the weight due to gravity of the elevator to cause the motion. This upwards force is the force produced by the strings pulling the elevator upwards.

2. The downwards force is the weight of the elevator which is being imposed due to the gravity of the Earth to pull everything towards it, and the mass of the elevator. This downward force is less than the upward force.

3. When the elevator stops, the upward force and downward force are equal but opposite in magnitude.

Final answer:

An elevator experiences tension in the supporting cable, weight of the elevator, upward force from the floor, and gravitational force as it moves upward from rest. As it accelerates, the tension in the cable is larger than the weight making the elevator and its occupants feel heavier. Conversely, as it decelerates to stop, they feel lighter due to reduced force exerted on the floor and scale.

Explanation:

When an elevator moves upward from rest to it's designated floor, it experiences several forces. The primary forces here include the tension in the supporting cable (T or I), the weight of the elevator (we), the upward force from the floor of the elevator or the normal force (N or Ñ), and the gravitational force which is usually represented by the weight of the person (w) and the weight of the scale (ws).

While the lift is still or moving at a constant speed, the tension in the cable (T or I) and the weight of the elevator are equal but opposite, so they cancel out. But, as the elevator begins to ascend, the tension in the cable must overcome the weight hence it's larger causing the elevator to accelerate upwards. When the elevator approaches the destined floor and begins to decelerate, the tension eases and becomes lesser than the weight.

In relation to the person in the elevator, when the elevator is at rest or moving at consistent speed, the person experiences their normal weight. When the elevator accelerates upwards, the person feels slightly heavier due to the increased force they exert on the floor (Fp or I) and subsequently on the scale (Fs). When the elevator decelerates to stop, the force they exert on floor and scale becomes less and, thus, they feel slightly lighter.

Which of the following conversion factors would you use to change 18 kilometers to meters? A.) 1,000 m/1 km
B.) 1 km/1,000 m
C.) 100 m/1 km
D.) 1 km/100 m

Answers

Answer:

The answer is A) 1,000 meters = 1 Kilometer.

Explanation:

To convert 18 Kilometers into meters, one would have to multiply the figure given in Kilometer by 1000.

Therefore we have 18 x 1000

= 18,000.

So 18 Kilometers is also 18,000 meters when converted.

Cheers!

use choice B. 1 km / 1000 m

from what result that 18 km = 18 000 m

Use newton's first law of motion to explain why you feel tossed around whenever a roller coaster goes over a hill or through a loop.

Answers

Newton's first law states that an object at rest will stay at rest && an object in motion will remain in motion unless acted on by another force. With that being said you feel tossed around because you are initially at rest but when you ride the roller coaster you take it's course of motion.

Hoped this helped!

Explanation:

A roller coaster is hard to stop because it has a lot of inertia. Inertia can be simplified to, "objects want to keep doing what they are doing." It's when they are forced to do something different that they are doing that is why roller coaster riders experience the float or tossing around of the ride.

A 50 Kg football player is standing still when he experiences an inelastic collision with a 150 Kg football player who is traveling at 10 m/s. What is the velocity of the player immediately after the collision?

Answers

Answer:

V = 7.5 m/s

Explanation:

Given that,

Mass of player 1, m₁ = 50 kg

Mass of player 2, m₂ = 150 kg

50 kg player stands still and 150 kg player is traveling at 10 m/s

We need to find the velocity of the player immediately after the collision. As the inelastic collision occurs. The linear momentum will remain conserved. After the collision, let they move with a constant velocity say V.So,

$m_1u_1+m_2u_2=(m_1+m_2)V\n\nV=(m_1u_1+m_2u_2)/((m_1+m_2))\n\n=(150* 10)/((50+150))\n\n=7.5\ m/s$
