Explanation:

Hi there!

From the question;

Mass (m)= 88kg

Acceleration due to gravity (g)= 9.8m/s²

Then;

Weight (W) = m*g

                  = 88*9.8

                  = 862.4 N

Therefore, the weight of refrigerator is 862 N.

Answer: Option A.

Hope it helps!

The weight of the refrigerator is 862.4 N. So, the correct answer is option A.

The acceleration an object experiences as a result of gravitational force is known as acceleration due to gravity.

Here,

Mass of the refrigerator, m = 88 kg

Acceleration due to gravity, g = 9.8 m/s²

The weight of an object is defined as the gravitational force that pulls the masses of the Earth towards its centre.

Weight of the object is the product of its mass and the acceleration due to gravity.

Therefore, the weight of the refrigerator,

W = mg

W = 88 x 9.8

W = 862.4 N

Hence,

The weight of the refrigerator is 862.4 N. So, the correct answer is option A.

Answer:

The trebuchet was invented in France and was first reported to be used in 1124AD in the siege of Tyre (in present-day Lebanon) during the Crusades. As it was much more powerful than a catapult, a trebuchet became the siege weapon of choice.

Explanation:

Most people think that the trebuchet is a medieval weapon, but actually, it has its origins in ancient China. The ancient Chinese trebuchet could throw huge boulders up to 250 pounds, a distance of 200 feet. In addition, it was lightweight and mobile which was crucial as it could be moved around the battlefield with ease. The thing I love about the chinese trebuchet is that it pushes the boundaries of ancient engineering to create a ballistics revolution - a flexible, portable, killing machine.

The average force the wall exerts on the ball is 180.4 N

From the question given above, the following data were obtained:

We'll begin by calculating the impulse. This can be obtained as follow:

I = m(v + u)

I = 0.055 (19 + 22)

I = 0.055 × 41

I = 2.255 Ns

I = Ft

2.255 = F × 0.0125

Divide both side by 0.0125

F = 2.255 / 0.0125

F = 180.4 N

The block on the table will move towards the right when the given unbalanced force act on the object. Option C is correct.

When the force acting on the object is not equalized by the opposite force.

It is defined as the vector sum of all forces acting on the object at an instance.

[tex]F = \vec F_1+\vec F_2+.....[/tex]

Where,

[tex]F[/tex] - net force

[tex]\vec F_1[/tex] - Force acting on the right = 10 N

[tex]\vec F_2[/tex] - Force acting towards left = -8 N

Put the values in the formula,

[tex]F = 10 +(-8)\\\\F = 2[/tex]

Since the net force is positive it means the move towards the right.

Therefore, the block on the table will move towards the right when the given unbalanced force act on the object.

Based on scientific data, the stone is accelerated at approximately 10 [tex]m/s^2[/tex].

Given the following data:

Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.

This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.

Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.

According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 [tex]m/s^2[/tex].

In this scenario, the stone is accelerated at approximately 10 [tex]m/s^2[/tex].

Answer:

Relative to the ground, the velocity of the aircraft is 240 km/hr

Explanation:

Relative velocity is different from normal velocity;

When 2 objects are moving in opposite directions towards each other, they will appear to be faster than they actually are;

This is known as the relative velocity;

The information tells us we have the aircraft moving 320 km/hr northwards relative to the wind;

The wind is in the opposite direction at 80 km/hr;

R = relative velocity of the aircraft

v = actual velocity of the aircraft

w = velocity of the wind

R = v + w

Note: if the wind was moving in the same direction, the formula would be R = v - w

320 = v + 80

v = 320 - 80

v = 240

The velocity relative to the ground is simply the actual velocity as the ground doesn't move;

So, relative to the ground, the velocity of the aircraft is simply 240 km/hr

Formula for speed: Speed = Distance/Time

So apply the formula here... 320m/80s

320 divided by 80 gives us 4 so...

Clara's average speed is 4 meters per second

Answer:

Explanation:

Hi there!

Recall the following relationships:

[tex]W = \Delta U = mg\Delta h\\\\P = \frac{W}{t}[/tex]

W = Work (J)

U = Potential Energy (J)

m = mass (kg)

g = acceleration due to gravity (9.8 m/s²)

h = height (m)

t = time (s)

Begin by calculating the work:

[tex]W = 50(10)(8) = 4000 J[/tex]

Now, divide by the time to solve for power:

[tex]P = \frac{4000}{5} = \boxed{800W}[/tex]

**W is the unit for power (Watts).  Be careful not to get the two confused.

Answer:

the earth is larger and has a much stronger gravitational force than the moon. Due to its size, speed, and core. It allows us to live here and walk like normal. But on the moon there is next to none. just enough force to keep it nearby. You can throw a ball 300x further on the moon than on earth. But overall the biggest difference is that ours can hold atmosphere while the moon cannot.

Answer:

The gravitational force is a force that attracts any two objects with mass.

Earth's average surface gravity is about 9.8 meters per second per second

whereas

The Moon's surface gravity is about 1.6 meters per second per second.

that means

The Moon's surface gravity is weaker because it is far less massive than Earth.

so as a result

The gravitational force on Earth is much more stronger than Moon
