Answer:

5376 meters per 32 seconds.

Explanation:

Multiplied 2.8 by 60 Making it 168 m/m. Then multiplied that by 32, since it’s 32 minutes, and got 5,376 meters per 32 minutes.

Speed, distance and time can be calculated using a magic triangle. D (the distance) goes in the top of the triangle, S (speed) goes in the bottom left of the triangle and T (time) goes in the bottom right of the triangle.

The combination of a particle's mass and velocity produces momentum. Momentum is a vector quantity that has both magnitude and direction. The force exerted on a particle is equated to the time rate of change of momentum by Isaac Newton's second equation of motion.

First law of Newton : According to Newton's first law of motion, if a body is at rest or moving in a straight path at a constant speed, it will stay in that state or continue to move in that direction unless it is acted upon by an outside force.

Second law of Newton : According to Newton's second rule of motion, a body's rate of momentum change is inversely proportional to the force acting on it, and momentum changes occur in the direction of the net applied force.

Third law of Newton : Newton's third law of motion states that there is always an equal and opposite reaction to every action.

In order to accomplish work and to produce heat and light, energy must be transferred to a body or to a physical system. Energy is the quantitative attribute that does this.

A push or pull that an object experiences as a result of its interactions with its environment is known as a force.

Dust and smoke rising in the atmosphere as a result of an asteroid impact hinder sunlight from reaching our planet, resulting in a decrease in global temperature. Many living beings could die as a result of this incident. A small city might be destroyed if an asteroid the size of an apartment strikes Earth. A 20-story building-sized asteroid might wipe out a small nation if it were to strike Earth.

The ship travels with a velocity of 15 km/h within 2 hours. The distance travelled is the velocity times the time taken that is 30 km to the north.

Velocity is a physical quantity measuring the distance travelled by an object per unit time. Velocity is the rate of speed and it is a vector quantity having both magnitude and direction. The unit of velocity can be m/s, km/h, ft/s etc.

Velocity is the ratio of the change in distance to the change in time. The change in distance is sometimes called the displacement.

then velocity  = displacement / time

Given that velocity = 15 km/h

time taken = 2 hours

then displacement = velocity × time

= 15 × 2 = 30 Km

Therefore, the displacement of the ship is 30 km to the north.

Answer:

The lens can sharpen the curvature of its front and back surfaces, increasing its focusing power.

Explanation:

A lens can change its refractive power through sharpening of the curvature of its front and back surfaces, thereby increasing its focusing power.

The optical power of a lens is the degree to which the lens is able to converge or diverge light.

The optical power of a lens is measured in Diopters, and obtained by taking the reciprocal of the focal length in meters.

Answer: D 100N

Explanation: Subtract the length of the beam by the pivot and multiply the weight by it.

Explanation:

the magnitude of the resultant force =

√(68.9² + 85.4²)

=√(4,747.21 + 7,293.16)

=√12,040.37

= 109.7 N

»Sue's style feet (north) = 68.9N

»Jenny style feet (East) = 85.4N

So, the resultant force on the ball is

= √(68.9² + 85.4²)

= √(4,747.21 + 7,293.16)

= √(12,040.37)

≈ 109.72N✅

Hi there!

Because of Newton's Third Law, the force exerted by the sprinter on the track is equal and opposite to the force exerted by the track on the sprinter.

We can begin by calculating the sprinter's acceleration. Use the equation:

vf² = vi² + 2ad

Rearrange for acceleration:

(vf² - vi²)/2d = a

Plug in values:

(8² - 2²)/2(2.5) = 60/5 = 12 m/s²

Calculate the force:

∑F = ma

∑F = 60 × 12 = 720 N. This is the amount of force exerted by the track on the sprinter in causing him to accelerate forward.

Thus, the backward force exerted by the sprinter on the track is the opposite, or -720 N.

Answer:

The force formula is defined by Newton's second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m×a( force = mass×area)
