How is a circuit formed
Answer:
An electrical circuit is composed of a source of electrical power, two wires that can carry electric current, and a light bulb. One end of both the wires is attached to the terminal of a cell while their free ends are connected to the light bulb. The electrical circuit is broken when the bulb is switched off.
What’s the difference between mechanical and chemical weathering
Answer:
Mechanical weathering is the physical breakdown of rock into smaller pieces. Chemical weathering is the breakdown of rock by chemical processes.
Explanation:
Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition. The smaller pieces have the same minerals, in just the same proportions as the original rock.
Chemical weathering is the other important type of weathering. Chemical weathering is different from mechanical weathering because the rock changes, not just in size of pieces, but in composition Chemical weathering works through chemical reactions that cause changes in the minerals.

How much impulse is applied by a 25 N force in 30 seconds?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Impulse.
Impulse is denoted by 'J'
hence, J = F. dt
so we get as,
J = (25)*(30)
J = 750 N-s
===> hence the impulse is 750 N-s
Impulse is applied by a 25 N force in 30 seconds is 750 N-s.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Answer:
Magnetism is one aspect of the combined electromagnetic force. It refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects.
10-kg box is sliding across an ice rink at 10 m/s . A skater exerts a constant force of 10 N against it. How long will it take for the box to come to a complete stop?
Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.

A car travels along a straight road to the east for
100 meters in 4 seconds, then has to turn around
and goes back west for 50 meters in 1 second.
Determine average speed and average velocity.
Answer: 90 m/s, 70 m/s
Explanation:
Given
A car travels 100 m east for 4 seconds and then turn around
goes back west for 50m in 1 sec
Distance traveled in the east is [tex]100\times 4=400\ m[/tex]
Distance traveled in the west is [tex]50\times 1=50\ m[/tex]
Total distance[tex]=400+50=450\ m[/tex]
total displacement[tex]=400-50=350\ m[/tex]
total time [tex]t=4+1=5\ s[/tex]
Average speed
[tex]\Rightarrow s_{avg}=\dfrac{\text{distance}}{\text{time}}=\dfrac{450}{5}\\\\\Rightarrow s_{avg}=90\ m/s[/tex]
Average velocity
[tex]\Rightarrow v_{avg}=\dfrac{\text{displacement}}{\text{time}}=\dfrac{350}{5}\\\\\Rightarrow v_{avg}=70\ m/s[/tex]
What distance separates Earth and the Sun? A 300,000 km per second B Eight light-minutes C 149 million light-seconds D One light-year
Answer:
B Eight light-minutes
Explanation:
In the case when the distance separated earth and the sun so here we orbit the sun for a 150 million km distance and the light moves would be 300,000 kilometers per second
Now divide this
= 150 million ÷ 300,000 kilometers per second
= 500 seconds
This 500 seconds represent 8 minutes and 20 seconds
Hence, option B is correct
Answer:
B) Eight light-minutes
How fast will a 1200 kg car be travelling when its momentum is 2400 kgm/s?
Answer:
Slow
Explanation:
The equation is:
p = mv
m = 1200
p = 2400
2400 = 1200v <-- divide both sides by 1200
v = 2 m/s
