Answer:

Distance, d is 86.1 meters.

Explanation:

Given the following data;

Time, t = 6.15secs

Velocity = 14m/s

Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.

Mathematically, velocity is given by the equation;

[tex]Velocity = \frac{distance}{time}[/tex]

[tex]V = \frac{d}{t}[/tex]

[tex]d = Vt[/tex]

Substituting into the above equation;

[tex]d = 14 * 6.15[/tex]

d = 86.1m

Hence, the distance traveled by the boat is 86.1 meters.

The torque produced by the force is 2 Nm

This is the turning effect of a force.

The torque of a force is given by τ = Fd where

Since τ = Fd,

Substituting the values of the variables into the equation, we have

τ = Fd

τ = 10 N × 0.2 m

τ = 2 Nm

So, the torque produced by the force is 2 Nm

Answer: A basketball is something that can have a physical or chemical change done to it.

Explanation:

A basketball is made of matter. The fire itself is not a matter however, the wood that burns is matter. A basketball is very different from a fire because a basketball has some mass in it on the other hand fire does not contain any mass

Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma.

These different states of matter have different characteristics according to which they vary their volume and shape.

For any substance to be considered as matter it must have to contain some mass and occupies some space.

As given in the problem statement a basketball is made of matter. The fire itself is not a matter however, the wood that burns is matter. A basketball is very different from a fire because a basketball has some mass in it on the other hand fire does not contain any mass.

The efficiency of the torch light from the total energy supplied and useful energy is 46.7%.

The efficiency of the torch is the amount of energy used to produce light compared to the total energy supplied to the torch light. This can also be called useful energy.

Total energy supplied to the torch = 150 J

Total energy used to produce light = 70 J

The efficiency of the torch light is calculated as follows;

Efficiency = 70/150 x 100%

Efficiency = 46.7%

Thus, the efficiency of the torch light from the total energy supplied and useful energy is 46.7%.

Answer: Ernest Rutherford's

Answer: 1.5 km/s²

Explanation:

Given that,

Initial speed Vi = 0 km/s

Final speed Vf = 12km/s

Acceleration A = ?

Time taken T = 8 seconds

Recall that acceleration is the rate of change of velocity per unit time

i.e acceleration = (Vf - Vi)/T

A = (12km/s - 0km/s) / 8 seconds

A = 12km/s / 8 seconds

A = 1.5 km/s²

Thus, the acceleration of the rocket is 1.5 km/s²

Explanation:

A binary star system that is detected from the drop in luminosity as one star passes in front of the other is called eclipsing. It has two stars.

A binary system is a system composed of two stars that exert gravitational forces on a group of celestial bodies.

In a binary system, planets and celestial bodies can exhibit well-defined or irregular (very unstable) orbits.

The eclipsing binaries are stars where binary planets orbit in a plane containing the same line of vision, thereby eclipsing each other.

Explanation:

Answer:

m = 200 [kg]

Explanation:

To solve this problem we must use Newton's second law, which states that the sum of forces must be equal to the product of mass by acceleration.

ΣF = m*a

where:

F = force = 400 [N]

m = mass [kg]

a = acceleration = 2 [m/s^2]

400 = m*2

m = 400/2

m = 200 [kg]

the answer is 25N if u calculate it right the answer will be 25

The magnitude of the frictional force on the box is 25 N.

Frictional force is defined as the opposing force that resists the relative motion between surfaces.

Here,

Mass of the box, m = 10 kg

Force applied on the box, F = 55 N

Acceleration of the box, a = 3 m/s²

The frictional force, f opposes the applied force, F. So that the applied force must over come the frictional force in order to accelerate the box.

So,

F - f = ma

Frictional force, f = F - ma

f = 55 - (10 x 3)

f = 55 - 30

f = 25 N

Hence,

The magnitude of the frictional force on the box is 25 N.

Explanation:I remember having this as a hw and this was the answer correct me if I was wrong

From Hooke's law, the length of the spring after extension and after the mass is attached is 1.788 meters. Option B is the answer.

Hooke's law state that in an elastic material, the force applied is directly proportional to the extension provided that the elastic limit is not exceeded.

Given that a 12.0 kg mass is attached to 1.2 m long spring with a spring constant of 200.0 N/m.

The given parameters are:

According to Hooke's law

F = Ke

But F = mg

mg = Ke

Substitute all the parameters into the formula to get extension e

12 x 9.8 = 200e

e = 117.6 / 200

e = 0.588 m

The length of the spring after extension and after the mass is attached will be

[tex]L_{2}[/tex] = [tex]L_{1}[/tex] + e

[tex]L_{2}[/tex] = 1.2 + 0.588

[tex]L_{2}[/tex] = 1.788 m

Therefore, the correct answer is option B because the length of the spring after extension and after the mass is attached is 1.788 meters.

If you have any queries please ask.

Answer:

Yes, it is possible

Explanation:

If possible, since Newton's laws are based on the motion of bodies that have mass. An example of how a vehicle can be moved on the moon was seen during lunar exploration where American astronauts drove a buggy-cart on the moon for a period of time.

We must remember that Newton's Second Law tells us that force is equal to the product of mass by acceleration. In this way we have:

F = m*a

where:

F = force = [N]

m = mass [kg]

a = acceleration [m/s²]

The force is produced by internal combustion or by electric action of the vehicle engine, the mass is the mass of the vehicle plus that of the crew member and the acceleration is the one that develops due to the change of speed, from rest to a certain speed.
