Answers

Answer 1

Answer: it would be too hot to live on and hard to get any oxygen from the ground because it doesn’t support life there.

Explanation:

science.

Answer 2

Answer:

On Mars, it is too cold to support life, the only existing water is at it's north and south pole in solid form (ice). It's atmosphere is about 100 times thinner than Earth's so it couldn't hold in any heat anyway.

What is the kinetic energy of the 2 kg ball just before it hits the ground, travelling 28 meters per second?

Use this formula: KE=0.5mv²

Kinetic Energy (KE) is measured in Joules (J)
Mass (m) is measured in kilograms (kg)
Velocity (v) is measured in meters per second (m/s)

A) KE = 0.5 x 28 x (2)2 = 556 J
B) KE = 0.5 x 2 x 28 x 2 = 56 J
C) KE = 0.5 x 2 x (28)2 = 784 J
D) KE = 28 x 2 x (0.5)2 = 14 J

Answers

Answer:

The correct answer is C) KE = 0.5 x 2 x (28)2 = 784 J.

This is because the kinetic energy of an object is equal to one half times the mass multiplied by velocity squared.

In this case, the mass of the ball is 2 kg and the velocity is 28 m/s, so the equation would be KE = 0.5 x 2 x (28)2 = 784 J.

Answer:

KE = 784 J

Explanation:

ke= 0.5x2kgx28m/s

1156 g/L
= ________ kg/mL

Answers

The Answer is 0.001156.

To convert g/L to kg/mL, we need to divide the value of g/L by 1000. Therefore:
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

Answers

Answer:

your answer is potential

Kinetic energy can never be greater than the potential energy in a pendulum

Explanation:

Please mark as brainliest

Kinetic energy can never be greater than the potential energy pendulum. A moving object as well as particle has kinetic energy.

What is kinetic energy?

Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, being done on it by exerting a net force.

A moving object as well as particle has kinetic energy, which relies on both its mass and its rate of motion. The type of motion might be vibration, rotation on an axis, translation (or travel along a path through one point to another), or indeed any combination of these. Kinetic energy can never be greater than the potential energy pendulum.

Therefore, kinetic energy can never be greater than the potential energy pendulum.

Scientists have discovered a colony of potential organisms on the Planet Moby and named them "Maxoids." Read the information below that scientists have gathered on Maxoids and decide whether Maxoids are living or nonliving things. Explain how you came to this conclusion.

Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.

Answers

The Maxoids are living things because they possess the characteristics of living things.

I hope u find the right path

Explanation:

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

Answers

Answer:

Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.

Table B: Calculation of Kinetic Energy (KE)

Table B: Calculation of Kinetic Energy (KE)

Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500

To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.

For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2

Perform similar calculations for the other velocities and record the results in Table B.

Answer:

Explanation:mass of the bottle in each case is M = 0.250 kg

now as per given speeds we can use the formula of kinetic energy to find it

1) when speed is 2 m/s

kinetic energy is given as

2) when speed is 3 m/s

kinetic energy is given as

3) when speed is 4 m/s

kinetic energy is given as

4) when speed is 5 m/s
