CAN SOMEONE HELP WITH THIS QUESTION PLSSS!

Acceleration due to gravity depends directly on the mass of Earth and inversely to the square of radius of Earth.

Answer:

9.8 m/s2

Explanation:

Acceleration due to gravity is the acceleration gained by an object due to the gravitational force. Its SI unit is m/s 2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.

Answer:

Electromagnetic waves.

Explanation:

Electromagnetic waves include microwaves, X-rays, gamma rays, and light waves, it carries energy and it can travel through matter or empty space.

Answer:

Electromagnetic waves or Light Waves

Explanation:

"Electromagnetic waves carry energy. The waves consist of transverse vibrations in electrical and magnetic fields, not vibrating particles. Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum)."

...Bored so lol

Answer & Explanation:

Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite's motion. Whichever crash was a stronger force would cause it to change motion more. It takes a stronger force to change the velocity of a more massive object.

Answer:

The value is [tex]R_{max} = 33.54 \ m[/tex]

Explanation:

From the question we are told that

    The total time of flight is  [tex]t = 3.7 \ s[/tex]

Generally from kinematic equation

        [tex]v = u - g * \frac{t}{2}[/tex]

So v is the velocity at maximum height and the value is  v = 0 m/s

So

       [tex]0 = u - 9.8 * \frac{ 3.7}{2}[/tex]

=>   [tex]u = 18.13 \ m/s[/tex]

Here u  is the initial velocity of the dart as it leaves that gun  

Gnerally the horizontal range of the dart is mathematically represented as

         [tex]R = \frac{u ^2 sin 2\theta }{g}[/tex]

For maximum horizontal range the value of  [tex]\theta = 45^o[/tex]        

So

         [tex]R_{max} = \frac{ 18.13 ^2 sin 2(45) }{9.8}[/tex]

=>     [tex]R_{max} = 33.54 \ m[/tex]

Answer:

I'm going to try to explain it to you easy as possible so basically when a motor is placed between two poles of another magnet a current from a voltage flow to the coil and a magnet field is produced around the electromagnetic and the poles of the magnet interact with the poles from the electricmatic causing the motor to turn in more coils growing stronger into the motor

Answer:

The ground pushes back on your feet with equal force

Explanation:

When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.

This interpretation and knowledge is gotten from Newton's third law of motion.

It states that "action and reaction force are equal and opposite in nature".

Answer:

the answer is the second one: the ground pushes back on your feet with equal force

Answer:

a change in velocity can be a change in magnitude (or speed), but it can also be a change in direction.

Answer:

The inner, rocky planets are smaller than the outer, gaseous planets

Explanation:

The relationship between the sizes of the planets and their distances from the Sun is: The smaller planets are closer to the sun while the bigger planets are farther from the sun.

A solar system can be defined as a collection of both the inner and outer planetary bodies alongside the Moon in orbit (travel) around the Sun, in slightly elliptical orbits.  

Basically, the nine (9) planets of the solar system orbiting (traveling) in order of their distance around the Sun are;

Basically, the relationship between the sizes of the planets and their distances from the Sun is that the smaller planets are closer to the sun while the bigger planets are farther from the sun.

Answer:

Friction force always acts tangent to the surface at points of contact. Friction force acts opposite to the direction of motion. There are 2 types of friction: Static friction: If the two surfaces in contact do not move relative to each other, one has static friction.

Answer:

Yes, it will float.

Explanation:

It is given that,

A liquid has a density of 0.85 g/cm³.

We know that, the density of water is 1 g/cm³.

The density of the liquid is less than that of water. If the density of the liquid is less than that of water, it will float in it. Hence, if you pour some of the liquid into a glass of water, it will float.

Answer:it would make it thicker

Explanation:

Answer:

"The equation shows that the current in a circuit is inversely proportional to the resistance of the circuit. An increase in resistance would result in a decrease in current. And the factor by which the resistance increases is the same factor by which the current decreases."

Explanation:

Because it's just like wearing a glove/mitten when getting something out of the oven, because of the insulation from the glove/mitten, it reduces the heat that gets through into your hand, and it protects it. Just like what the "answer" says, it said that the resistance would decrease current.

Answer:

1. Static friction = not moving

2.  sliding friction = moving

Answer: When you hit a ball with a bat or racquet, work is done. A runner does work when they accelerate and acquire kinetic energy. Once that kinetic energy is achieved, work continues to be done just to overcome friction and maintain speed. Energy comes from the food they eat.
