an object with a mass of 6 kg accelerates 4 m/s2 when an unknown force is applied to it. what is the amount of the force?

Answer:

52 kilometers

Explanation:

Since we know that there are 1,000 meter in 1 kilometer, we can divide 52,000 by 1,000 (because we want know that every 1,000 meter is 1 kilometer).

52,000/1,000= 52 kilometers

That's your answer.

Hope this helped! :)

Newton’s Three Laws of Motion has a great impact.

Explanation:

Newton’s Three Laws of Motion has a great impact on the bowling game for the 2 students. When the student one throw ball to the student 2, the ball decrease its speed due to the gravity and opposing air. If these forces are removed from the system the ball will continue its motion till another force is applied on it. When the force applied to the ball it produces acceleration in the direction to the applied force. If the ball touches the ground it bounce back with equal force which is a reaction of the ground.

Explanation:

Visible light has a wavelength that ranges from 380 nm – 750 nm on the electromagnetic spectrum while infrared light is just beyond it, ranging from 700 nm – 1 mm, the start of the non-visible portion of the spectrum. As a result, infrared cannot be seen except with special equipment like a security camera

Visible light is the common lighting method and we see it all around us. It is used in homes, work areas, factory floors, parking lots, loading docks, etc. They are also used as warning systems and to provide lighting for CCTV cameras in public places. The presence of floodlights warns intruders that their actions are being monitored.

Infrared light, however, is used when the intention is to monitor intruders covertly. Without a bright light to warn them about the presence of security cameras, intruders no longer feel the need to avoid surveillance, leaving them exposed to the IR-illuminated cameras.

Answer:

1. For humans, we can only see visible light, but can't see infrared.

2. Infrared have longer wavelengths than visible light.

A snow blower is more powerful because it's easier, and it moves large amounts of snow easily. Shoveling uses all of your power. It can be difficult and it takes a long time to get the snow off of your lawn.

Therefore, using a snow blower is more powerful than using a shovel.

Answer and Explanation in one:

In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. So basically, you could possibly demonstrate with a variety of examples. One example may be just sitting on a table, waiting to get rolled off. I know it sounds silly, so here's another example. You are holding a bow and arrow, you pull back the arrow, aiming at the target. You are holding the arrow, filling it with potential energy. When it is let go, it is kinetic energy, the act of an object in motion, slowly riding of it's potential energy.

Answer:

Explanation: Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Answer:

[tex]\huge\boxed{\sf Inverse \ Relation}[/tex]

Explanation:

According to Newton's Second Law Of Motion:

"The acceleration produced by the body is directly proportional to the force acting on the body and inversely proportional to mass."

So, The Mathematical Form will be:

Acceleration ∝ [tex]\sf \frac{1}{mass}[/tex]

So, Acceleration and mass are inversely proportional. This means that Greater the mass, Smaller will be the acceleration produced and vice versa.

Answer:

A = 0.188 m²

Explanation:

First we find the distance between the plates by using the formula of electric field intensity:

E = ΔV/d

d = ΔV/E

where,

d = distance between plates = ?

ΔV = Potential Difference = 4 KV = 4000 V

E = Electric Field = 2 x 10⁸ V/m

Therefore,

d = 4000 V/(2 x 10⁸ V/m)

d = 2 x 10⁻⁵ m

Now, we find the Area of Plates by using formula of capacitance:

C = A∈₀∈r/d

where,

C = Capacitance = 0.25 μF = 0.25 x 10⁻⁶ F

A = Area of Plates = ?

∈₀ = Permittivity of free space = 8.85 x 10⁻¹² C/N.m²

∈r = Dielectric Constant = 3

Therefore,

0.25 x 10⁻⁶ F = A(8.85 x 10⁻¹² C/N.m²)(3)/(2 x 10⁻⁵ m)

A = (0.25 x 10⁻⁶ F)(2 x 10⁻⁵ m)/(3)(8.85 x 10⁻¹² C/N.m²)

A = 0.188 m²

Answer:

Explanation:

Let the direction of the south be -y

Let the direction of the east be +x

The displacement is gotten by using the pythagoras theorem as shown;

Let d be the displacement;

d² = x² + y²

Given

x = 45 yards

y = -80 yards

Substitute the given values into the expression;

d² = x² + y²

d² = 45² + (-80)²

d² = 2025 + 6400

d² = 8425

d = √8425

d = 91.79 yards

Hence the total displacement of the player is 91.79 yards

Answer:

1. Range = 153.42 m.

2. Maximum height = 54.78 m

3. Time of flight = 6.69 s

Explanation:

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

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

1. Determination of the range.

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

Acceleration due to gravity (g) = 9.8 ms¯²

Range (R) =?

The range i.e how far the ball went can be obtained as follow:

R = u² Sine 2θ /g

R = 40² × Sine (2×55) / 9.8

R = 1600 × Sine 110 / 9.8

R = 1600 × 0.9397 /9.8

R = 153.42 m

2. Determination of the maximum height.

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

Acceleration due to gravity (g) = 9.8 ms¯²

Maximum height (H) =?

H = u² Sine² θ / 2g

H = 40² × (Sine 55)² / 2 × 9.8

H = 1600 × (0.8192) ² / 19.6

H = 54.78 m

3. Determination of the time of flight

Initial velocity (u) = 40 ms¯¹

Angle of projection (θ) = 55°

Acceleration due to gravity (g) = 9.8 ms¯²

Time of flight (T) =?

T = 2u Sine θ / g

T = 2 × 40 × Sine 55 / 9.8

T = 80 × 0.8192 / 9.8

T = 6.69 s

Answer:

125 m

i just did the edpuzzle

Answer:

The magnitude of the work performed by the mover is 1863 J.

Explanation:

The work can be found using the following equation:

[tex] W = F*d [/tex]

Where:

F: is the force

d: is the displacement = 8.1 m

First, we need to find the net force in the horizontal direction, as follows:

[tex] \Sigma F_{x} = ma = 0 [/tex]

a = 0 since the mover slides a refrigerator at a constant velocity.

[tex] F_{x} = F_{f} = -230 N [/tex]

[tex]F_{f}[/tex]: is the friction force.

Then, the work is:

[tex] W = F*d = -230 N*8.1 m = -1863 J [/tex]    

Therefore, the magnitude of the work performed by the mover is 1863 J.

as the surface  area increases the rate of reaction  also increases.

Explanation:

Answer:

A.) The rate is faster.

C.) 28 Seconds

a)5m/s b)5

the 5 is because you add the seconds to get 8 seconds and then do the same with the distance to get 40. 40/8 = 5. speed = 5

Velocity = displacement/change in time

V = 40/8

Explanation:

Answer:

H = 234.85m

Explanation:

Using the formula for calculating range to find the maximum height

Range R = U√2H/g

U is the speed = 13m/s

H is the max height

R is the distance covered in horizontal direction

g is the acceleration

Substitute the given values as shown;

90 = 13√2H/9.8

90/13 = √2H/9.8

6.923 = √2H/9.8

6.923² = 2H/9.8

2H = 6.923²  *  9.8

2H = 469.70

H = 469.70/2

H = 234.85m

Hence the top level was 234.85m high
