suppose you are in a spacecraft traveling from earth to the moon. Will there be a point where the gravitational pull from earth and from the moon are equal? why?
Answers
Answer: There is no net force because the ship is beyond the influence of Earth and the Moon There is no net force because the forces erected by Earth and the Moon balance There is a net force because the force exerted by Earth is smaller than that exerted by the Moon.
Explanation:
Answer: there is a point in space between the earth and the moon where the force of gravity on an arbitrary object is equal in magnitude but opposite in direction and any object between the Earth and the Moon will be within the Sun's gravitational field. So there can be no point, where the gravitation field strength is zero

Answers
Answer: Option c
Explanation: Wind has kinetic energy to move objects from their places. It is vastly used across the world for the production of electricity.
By turning the kinetic energy of moving air into electrical, the wind is used to generate power. Wind drives the rotor blades of contemporary wind turbines, which transform kinetic energy into rotational energy. A shaft transmits this rotational energy to the generator, which generates electrical energy. More than a century ago, the first wind turbines appeared. After the electric generator was developed in the 1830s, engineers began experimenting with harnessing wind power to create electricity. However, modern wind power is thought to have been invented in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-meter wind turbine started operating in 1897. Wind power generation occurred in the United Kingdom and the United States in 1887 and 1888.

Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects.

Erin is keeping a science journal. She wrote the following paragraph that explains how light travels through different mediums. But she’s made one mistake. Which sentence in Erin’s journal is incorrect?
A ray of light passes through the air and enters the water inside a metal container. The light ray bends as it crosses the boundary between air and water. Once it hits the bottom of the container, the ray gets reflected. The reflected ray passes back through the water and enters the air without bending. In this example, the ray of light is both reflected and refracted.

A driver is driving a 6371 kg lorry. After spotting a hazard, the driver applies the brakes. The lorry decelerates uniformly and comes to a stop 60 m after the brakes are applied. Estimate the braking force needed to stop the lorry.
Answers
Answer:
The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.
Explanation:
To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).
In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:
Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)
Since vi = 0 and vf = 0, the equation simplifies to:
0 = 0 + 2 * a * d
Solving for acceleration (a), we have:
2 * a * d = 0
a = 0
Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.
The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.
The following steps will guide you on how to calculate the braking force:
Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.
Step 2: Determine the distance travelled by the lorry, which is 60 m.
Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.
However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.
This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t
Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.
Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at
Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.
Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

Answer:
hope my answer helps you mark me brianliest （⌒▽⌒）
Explanation:
Even you exert a gravitational force on other objects. Because your mass is so much less than the mass of the Earth, you can't feel your gravitational force. ... Because the Earth's gravity has the same pull on every object, all objects fall at the same speed (in a vacuum),and alsoGravity not only pulls on mass but also on light. Albert Einstein discovered this principle. If you shine a flashlight upwards, the light will grow imperceptibly redder as gravity pulls it. You can't see the change with your eyes, but scientists can measure it.
You are out and about in the country and your father sees a rock that he really wants in the yard. Now you must get the very heavy rock into the back of a truck. The truck bed is 3 feet off the ground. Your father pulls out a 5-foot plank and begins to set up a ramp. At the same time, you (who know about mechanical advantage!) have found a plank that is 8 feet long, and you show it to your father.
Which plank will give you the most mechanical advantage? Calculate the MA for each plank.
Answers
Plank that is 8 feet long will give more mechanical advantage than 5-foot plank .
What is mechanical advantage?The force amplified by utilizing a tool, mechanical device, or machine system is known as mechanical advantage.
mechanical advantage of a ramp = the length of the slope/ the height of the ramp.
Height = 3 feet ( fixed).
Hence, plank that is 8 feet long will give more mechanical advantage than 5-foot plank because the length of the slope is greater in the case of plank that is 8 feet long.
