Explanation:

A body is moving with a velocity of 15m/s . If the motion is uniform. How much distance will be the velocity after 10s

Answers

Answer:

Distance = 150 meters.

Explanation:

Given the following data;

Velocity = 15 m/s

Time = 10 seconds

To find the distance;

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]

Making distance the subject of formula, we have;

[tex] Distance = velocity * time [/tex]

[tex] Distance = 15 * 10 [/tex]

Distance = 150 meters

A pump is to lift 20.0 kg of water per minute through a height of 25.50 m. What output rating should the pump motor have?

Answers

Answer:

the output rating that should the pump motor have is 83.30 Watt

Explanation:

Given that

The pump lift 20 kg of water per minute having a height of 25.50 m

We need to find out the output rating that should the pump motor have

As we know that

power = energy ÷  time

=  m g h ÷ t  

=   20.0 × 9.8 × 25.50 ÷ 60  

=  83.30 Watts

Hence, the output rating that should the pump motor have is 83.30 Watt

According to Newton’s second law, the mass of an object is 120kg and it is accelerating at a rate of 5m/s2 . The object’s force would be

Answers

Answer:

F = 600 N

Explanation:

The second law is F = m * a

The mass (m) is in kg = 120

The acceleration in in m/s^2 = 5

The force is in Newtons.

m and a do not require any conversions. They are in the correct units.

F = 120 * 5

describe how you would determine the half-life of a substance from an activity/time graph, plsplspls help

Answers

Answer: At any time, the number of decays per reasonable

time unit is proportional to the amount of the isotope present. (This is expressed by the first-order rate equation for a one-decay process.) Therefore, it does not matter whether one looks at the amount or the number of decays. It may be easier to measure the number of decays by e.g. a Geiger counter and prefer it for that reason.

It now matters what you understand to be the rate: the number of decays per second or the percentage of nuclei decaying at any given time. The first becomes less over time, the second one is a constant for each isotope.

You must have a reasonable number of decays within your time unit. If the half-life is long, it makes little sense to look at millisecond slices.

If it takes 726 watts of power to move an object 36 m in 14 s, what is the mass of the object?

Answers

Answer:

Explanation:

Given

Power (p)= 726 watt

Time (t) = 14 sec

distance travelled (d; h) = 36 m

mass (m) = ?

we know

Power (p) = W/t  ( w = work done )

p = m * g * h / t  ( w = m * g* h)

726 = m * 10 * 36 / 14 ( g = 10 m/s^2)

m = 28. 23 kg

or if we use the value of g as 9.8 m/s^2

the mass will be

= 28.8 kg

hope it helps :)

The mass of the object if it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.

What is mass?

An object's inertia, a fundamental property, is measured by its mass, a fundamental indicator of the volume of substance inside the thing. Definitions of mass can seem circular since it is such a fundamental quantity and is challenging to define in terms of another.

It is possible to define every mechanical quantity in terms of mass, length, and time. The SI unit for mass, denoted by the letter m, is the kilogram. While mass is typically thought of as an immutable feature of an item, relativistic mass must be taken into account when traveling at speeds close to the speed of light.

Given:

The Power, p = 726 watt

The Time, t = 14 sec

distance travelled, d = 36 m

Calculate the power by the given formula

p = W / t  

p = m * g * h / t  ( w = m * g* h)

726 = m * 9.8 * 36 / 14 ( g = 10 m/s^2)

m = 28. 8 kg

Therefore,  the mass of the object If it takes 726 watts of power to move an object 36 m in 14 s is 28.8 kg.
