How can an electric current produce a magnetic field
Answer:
When the compass is placed below the wire, and the electric current switched on, the needle deflects in the opposite direction. If an electric current is passed through a long coil of wire (a solenoid ) a magnetic field is produced which is the same shape as that of a bar magnet.
Explanation:
Answer:
a changing electric field creates a magnetic field.
Explanation:
if you have a circuit and you send AC current through (AC = Alternating current) so that the electrons move back and forth, they will create a changing electric field.
This produces a magnetic field (because that's what the universe does).
Will an object experience a greater force of gravity on the earth or moon? Why?
Answer:
Earth’s gravitational force is stronger
Explanation:
Earth’s gravitational force is stronger than the moon because of the presence of more massive objects in earth; on the flip side, the moon’s gravity is weaker than the earth due to smaller in size as compared to the earth. Earth gravity is denoted by g; conversely, moon gravity is denoted by gm
Answer: The greater an object's mass, the more gravitational force it exerts. So, to begin answering your question, Earth has a greater gravitational pull than the moon simply because the Earth is more massive. That's why the moon isn't pulled out of Earth's orbit by the gravity of larger planets or by the sun.

Insect A moves 5.0 m/min and insect B moves
9.0 cm/s. Determine which insect is ahead
and by how much after 30 min. Assume both
insects are moving in the same direction.
Answer:
insect B by 12m
Explanation:
30min = 1800s (times by 60)
5m/min x 30min = 150m
9cm/s x 1800s = 16,200cm = 162m
162m - 150m = 12m
You get out of school and walk north for 20 minutes. You travel
1.6 km. What is your average velocity?
What is the
Answer:
[tex]\boxed {\boxed {\sf v= 0.08 \ km/min \ North}}[/tex]
Explanation:
Velocity is found by dividing the displacement by the time.
[tex]v=\frac{s}{t}[/tex]
where s is the displacement and t is the time.
The displacement is 1.6 kilometers, but it needs a direction as well. The question notes you walked North. The time is 20 minutes.
[tex]s= 1.6 \ km \ North \\t= 20 \ min[/tex]
[tex]v=\frac{1.6 \ km \ North} { 20 \ min}[/tex]
Divide.
[tex]v= 0.08 \ km/min \ North[/tex]
Velocity is a vector quantity, so that is why it has the measurement and the direction.
The average velocity is 0.08 kilometers per minute North.

What are the velocity and acceleration of the ball at the highest point in its path? What are the velocity and acceleration of the ball at the highest point in its path? V=0,a=0. V=0,a=9.8m/s2up. V=0,a=9.8m/s2down. V=9.8m/supa=0. V=9.8m/sdowna=0
Answer:
v = 0 and a = 9.8 m/s²
Explanation:
When an object reaches the highest point, its velocity is equal to 0. After reaching the highest point, it starts to decelerate. The acceleration is in the downward direction and it is equal to g i.e. 9.8 m/s².
So, the velocity and acceleration of the ball at the highest point in its path is 0 and 9.8 m/s² downward.
Hence, the correct option is (d).
A plate has an area of 1m square. It slide down an incline plane , having an angle of inclined 60° to horizontal, which a velocity of 0.75m/s. The thickness of oil film between the plate and the plate is 2mm. Find the viscosity of the fluid if the weight of the plate is 90N
Answer:
[tex]\mu =0.169704 Ns/m^2[/tex]
Explanation:
From the question we are told that
Area of plate[tex]a=1m^2[/tex]
Angle of inclination [tex]\theta=60 \textdegree[/tex]
Velocity [tex]v=0.75m/s[/tex]
Thickness of oil [tex]t=2mm[/tex]
Weight of plate [tex]w=90N[/tex]
Generally the equation for shear force is mathematically given by
[tex]F=mgsin45 \textdegree[/tex]
[tex]F=90sin45 \textdegree[/tex]
[tex]F=63.639N[/tex]
[tex]F=\mu* \frac{v}{t}[/tex]
[tex]F=\mu* \frac{0.75}{2*10^-^3}[/tex]
[tex]\mu* \frac{0.75}{2*10^-^3}=63.639N[/tex]
[tex]\mu =\frac{63.639}{375}[/tex]
Therefore viscosity is given by
[tex]\mu =0.169704 Ns/m^2[/tex]
help plss .. Two bicyclists are accelerating forward in a straight line, and Biker 1 has less
mass than Biker 2. If the net force on the bikers is the same, which statement
describes their acceleration?
Explanation:
Remember Newton's Second Law.
[tex]F=ma[/tex]
If the force acting on both bikers is the same, we can look at the relationship between acceleration and mass.
If Biker 1 has a mass of 10kg and Biker 2 has a mass of 20kg, and both are being acted upon by a force of 100 N, let's see what that looks like. [tex]100 = 10*a_1 \rightarrow a_1 = 100/10 = 10[/tex]
[tex]100 = 20 *a_2 \rightarrow a_2 = 100/20 = 5[/tex]
So, given the same force, an object with GREATER mass will have less acceleration.
Vivian went on a bicycle trip through Germany with her family. One afternoon, she rode her bicycle along a long flat road at a constant speed for 24 kilometers (km). The ride took her 1.2 hours (h). At what speed did she ride her bicycle?
Answer:
20km/h
Explanation:
Given parameters:
Distance moved = 24km
Time = 1.2hrs
Unknown:
Speed of her ride = ?
Solution:
Speed is the distance covered per unit of time.
So;
Speed = [tex]\frac{distance}{time}[/tex]
Speed = [tex]\frac{24}{1.2}[/tex] = 20km/h

Gravity influenced the formation of the solar system, with the planets orbiting the sun.
What is Gravitational Force ?Gravitational force is force of attraction between two masses. Gravitational force(F) between two bodies is directly proportion to the product of masses(m₁,m₂) of two bodies and inversely proportional to square of distance(r) between them. mathematically it is written as,
F [tex]\alpha[/tex] m₁.m₂
F [tex]\alpha[/tex] 1/r²
F = G m₁,m₂÷r²
where G is gravitational constant, whose value is 6.6743 × 10⁻¹¹ m³ kg-1s⁻².
Force is expressed in Newton N in SI unit. its dimensions are [M¹L¹T⁻²].
According to Kepler's first law of motion, every planet is moving in an elliptical orbit with sun has situated at one of the foci of the orbit.
when a planet moves in the orbit around the sun, it moves in a stable orbit. in this orbit , centripetal force is equal to centrifugal force, in this case centripetal force appears as gravitational force. Means Gravitational force between sun and planet balances the centrifugal force which is outwards. In such a way gravity influenced the formation of the solar system.
Hence gravity plays crucial role in the formation of solar system.
