Answer:

The SI unit of force is Newton.

Explanation:

Newton is denoted by N.

Force can be defined as the pull or push which change or try to change the state of a body from motion to rest or rest to motion in a straight line.

Answer:

For the first equation, the work done would be 60 J, but if it is done with 30 N, it would have been 90 J.

Explanation:

it's actually pretty easy one you practice it for some time. W ( work done in joules ) = F ( force put onto the object in newtons ) * D ( distance traveled in meters ).

Push is defined as a force that moves an object out of its resting position and away from the person exerting the push. When something is pushed, it usually moves away. Examples of push force include kicking a ball, shutting a door, pushing a cart, and plugging something in.

A push or pull that causes something to move is called a force. Every day, whether you're playing soccer, pushing a shopping cart, or pulling mittens onto your hands, you're moving objects!

An example of a push force is the force you use to push up against a wall. The force you use to pull a trolley vehicle is an example of pull force.

Every force is a push or a pull. A push occurs when an object is forced to move away from something. A pull occurs when an object is drawn toward you by force. Energy, friction, and gravity all have an impact on how strong or weak the force is.

Therefore, Once you practice it for some time, it's actually rather simple. Work in joules is equal to force on an object in newtons multiplied by D. (distance traveled in meters).

An atom is the smallest unit of ordinary matter that forms a chemical element.

Matter is composed of very tiny or microscopic particles called "Atom".

The rarefaction particles are further apart when the sound is soft. Do loud sounds travel faster than soft sounds? No. Both travel at the same speed.

Answer:

When an electromagnetic wave passes from space to matter, some part of the energy is absorbed by the matter and it increases its energy. The wave may reflect and some part may pass through the matter depending on the amount of energy they have. The amplitude of the wave decreases if some parts of it are reflected.

Electromagnetic radiation is one of the many ways that energy travels through space. The heat from a burning fire, the light from the sun, the X-rays used by your doctor, as well as the energy used to cook food in a microwave are all forms of electromagnetic radiation. While these forms of energy might seem quite different from one another, they are related in that they all exhibit wavelike properties.

Answer:

White light passes through a translucent pane of glass, and shines on a shirt. Both the translucent glass and the shirt appear green. ... The shirt reflects green so there is nothing for the shirt to absorb.

Explanation:

The white light that are not green are absorbed by the surface while the green light is scattered

Shirt will reflect green as their is nothing for the shirt to absorb

It is the process in which light is absorbed by matter and converted into energy

When white light falls upon a green  surface all the component of white light that are not green are absorbed by the surface while the green light is scattered, when that scattered light fall on white shirt , shirt will reflect green as their is nothing for the shirt to absorb

Answer:

the energy usage of the clock per year is 17.2 kWh

Explanation:

Given;

power drawn by the clock, P = 2 W

duration of the clock's operation, t = 8,600 hours per year

The energy usage of the clock per year is calculated as;

E = Pt

[tex]E = (\frac{2}{1000} )kW \ \times \ 8,600 \ hr\\\\E = 17.2 \ kWh[/tex]

Therefore, the energy usage of the clock per year is 17.2 kWh

Answer:

Because cosmic disaster are so vast, astronomers use light-years as their unit of distance. One light-year is defined as the distance a beam of light travels in one year. The nearest star is a little more than 4.37 light-years away from us. When we see light from a galaxy 2 million light-years away, it has taken 2 million Earth years to reach us. Light from the Sun takes approximately 8.4269 minutes to reach us

Explanation:

i) One light-year is defined as the distance a light beam travels in a time of one Earth year. One light year is equivalent to 6 × 10¹² miles or 9.7 × 10¹² km

ii) The distance to the nearest star =  4.37 light-years

iii) When a star located in a galaxy that is 2.3 million light years away is seen, it has taken 2.3 million light years to reach us

iv) The distance of the Sun to the Earth = 151.58 million kilometers

The speed of light, c = 299792.458 km/s

The time it will take light to reach us from the Sun, 't', is given as follows;

t = 151.58 × 10⁶ km/(299792.458 km/s) ≈ 8.4269 minutes.

Answer:

Higher percentage of runoff water is absorbed by the vegetation whereas 100 % of water runoff on the roofed area.

Explanation:

Higher percentage of runoff water is absorbed by the vegetation and very little amount of runoff water is received on the end of vegetative cover while on the other hand, 100 percent of precipitation water runoff on the surface of roofed or paved area because no water is absorbed by the roof due to its solid surface. The percentage of runoff depends on the factors such as rainfall intensity, slope, soil water storage capacity, and infiltration rate.

Answer:

The maximum height reached by the body is 313.6 m

The time to return to its point of projection is 8 s.

Explanation:

Given;

initial velocity of the body, u = 78.4 m/s

at maximum height (h) the final velocity of the body (v) = 0

The following equation is applied to determine the maximum height reached by the body;

v² = u² - 2gh

0 = u² - 2gh

2gh = u²

h = u²/2g

h = (78.4²) / (2 x 9.8)

h = 313.6 m

The time to return to its point of projection is calculated as follows;

at maximum height, the final velocity becomes the initial velocity = 0

h = v + ¹/₂gt²

h = 0 + ¹/₂gt²

h =  ¹/₂gt²

2h = gt²

t² = 2h/g

[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 313.6}{9.8} }\\\\t = 8 \ s[/tex]

Answer:

Potential difference = 8 Volts

Explanation:

Given the following data;

Power = 12 Watts

Current = 1.5 A

To find the potential difference;

Power = current * voltage

12 = 1.5 * voltage

Voltage = 12/1.5

Voltage = 8 Volts

Therefore, the potential difference which is the same as voltage is 8 Volts.

Answer:

q = - 2.26 x 10⁻⁶ C

According to answering format:

q = - 2.26

Explanation:

The potential at a distance r from a charge q is given as follows:

[tex]V = \frac{kq}{r}[/tex]

where,

V = Potential = -3680 V

k = Colomb's Constant = 9 x 10⁹ Nm²/C²

r = distance = 5.54 m

Therefore,

[tex]-3680\ V = \frac{(9\ x\ 10^9\ Nm^2/C^2)q}{5.54\ m}\\\\q = \frac{(-3680\ V)(5.54\ m)}{9\ x\ 10^9\ Nm^2/C^2}[/tex]

q = - 2.26 x 10⁻⁶ C
