Answer:
Electricity works by getting a bunch of conductor elements together and creating a flow of electron-stealing patterns through them. This flow is called a current. Conductors need to be surrounded with insulators so the electrons can only go in one direction.
Explanation:
A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of the loop in which the plane is flying?
Answer:
The radius of the curve is 9,183.67 m.
Explanation:
Given;
velocity of the jet plane, v = 600 m/s
acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²
The radius of the curve is calculated from centripetal acceleration formula as given below;
[tex]a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m[/tex]
Therefore, the radius of the curve is 9,183.67 m.
all of u what is the cause for moving object to speed up or down
Answer:
Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.
Explanation:
A 50Kg girl jumps off a 5-meter-high diving board. What is her kinetic energy right before she hits the water?
Answer:
2450 J
Explanation:
Given that,
A 50Kg girl jumps off a 5-meter-high diving board.
We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,
[tex]K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J[/tex]
So, her kinetic energy right before she hits the water is equal to 2450 J.

(a) If a person can jump a maximum horizontal distance (by using a 45° projection angle) of 3.0 m on Earth, what would be his maximum range on the Moon, where the free-fall acceleration is g/6 and g 5 9.80 m/s2 ? (b) Repeat for Mars, where the acceleration due to gravity is 0.38g.
Answer:
See explanation
Explanation:
Range of a projectile is given by; U^2sin2θ/g
When θ = 45°
The maximum range is obtained as;
Rmax = U^2/g
Maximum range on earth = RME = U^2/g
Maximum range in the moon= RMM =U^2/g/6
Maximum range in Mars = RMMA = U^2/0.38g
a)
RME/RMM = U^2/g/U^2/g/6
RME/RMM = 6
But RME = 3 m
RMM = 3 * 6 = 18 m
b)
RME/RMMA =U^2/g/U^2/0.38g
RME/RMMA = 1/0.38
But RME = 3 m
RMMA = 3/0.38
RMMA = 7.9 m

Big Ben, a large artifact in England, has a mass of 1x10^8 kilograms and the Empire State Building 1x10^9 kilograms. The distance between them is about 5,000,000 meters. What is the force exerted by Big Ben on the Empire State Building?
Answer:
The force, exerted by Big Ben on the Empire State Building is 2.66972 × 10⁻⁷ N
Explanation:
The question relates to the force of gravity experienced between two bodies
The given parameters are;
The mass of Big Ben, M₁ = 1 × 10⁸ kg
The mass of the Empire State Building, M₂ = 1 × 10⁹ kg
The distance between the two Big Ben and the Empire State Building, r = 5,000,000 meters
By Newton's Law of gravitation, we have;
[tex]F=G \times \dfrac{M_{1} \times M_{2}}{r^{2}}[/tex]
Where;
F = The force exerted by Big Ben on the Empire State Building and vice versa
G = The universal gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²
M₁, M₂, and r are the given parameters
By plugging in the values of the parameters and the constant into the equation for Newton's Law of gravitation, we have;
[tex]F=6.67430 \times 10^{-11} \times \dfrac{1 \times 10^8 \times 1 \times 10^9}{(5,000,000)^{2}} = 2.66972 \times 10^{-7}[/tex]
The force, 'F', exerted by Big Ben on the Empire State Building is F = 2.66972 × 10⁻⁷ N.

what causes lightning?
Answer:
cause by imbalances between stroms cloud and grounds , or within the cloud themselves.
Explanation:
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
The positive and negative charges grow large enough, a giant spark lightning, occurs between the two charges within the cloud.
What is lightning?The naturally occurring electrostatic discharge with high voltage for short duration from the cloud to the ground or within the cloud. The lightning can be seen by a flash of light that could be followed by the strong sound. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground or within the clouds. In the starting stages air acts as an insulator, but after the charges build up with the charges in the ground and cloud there will be the rapid form of electricity causes lightning. These lightning were in the color of bluish white.
Thus, the charges discharging naturally causes lightning.

A force of 31 N south is used to accelerate an object uniformly from rest to 8 m/s in 22 s. What is the mass of the object?
this question is centered around newtons second law f=ma
First you need to find the acceleration
[tex] acceleration = \frac{8 - 0}{22} [/tex]
that gives you 0.36 recurring(on both numbers) m/s²
mass= force ÷ acceleration
[tex] mass = \frac{31}{0.36recurring} [/tex]
mass= 85.25 kg
if you want to check
f=ma
85.25 × 0.36 recurring (remember its on both numbers not just 6) = 31 N
Answer:
Explanation:
Givens
F = 31 N
vi = 0
vf = 8 m/s
t = 22 seconds
m = ?
Formula
F = m ( vf - vi)/t
Solution
31 = m (8 - 0) / 22 Multiply both sides by 22
31 * 22 = 8 * m
8m = 682 Divide by 8
m = 682 / 8
m = 85.25
A flat screen TV uses 120 Watts. How much energy is used up if it is left on for 15 minutes? Question 25 options: 4 J 15 J 0.67 J 108,000 J
Answer:
Option d (108,000 J) is the correct answer.
Explanation:
The given values are:
Power,
P = 120 Watts
Time,
t = 15 min.
i.e.,
= 900 sec
As we know,
⇒ [tex]P=\frac{W}{t}[/tex]
So,
⇒ [tex]W=P\times t[/tex]
On substituting the given values, we get
⇒ [tex]=120\times 900[/tex]
⇒ [tex]=108,000 \ J[/tex]

Two magnets are held apart. Once released, the south pole of one magnet moves toward the north pole of another magnet until the magnets collide. How does the graph reflect the changes in energy that occur?
(1 point)
Kinetic energy is at its peak when the magnets are first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.
The kinetic energy of the system is derived from the thermal energy created by increased velocity. Energy stored in the magnetic field does not change.
Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Graph for the two magnets held apart, kinetic energy is highest when the magnets first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.
What is magnetic field?The magnetic field is the field in the space and around the magnet in which the magnetic field can be filled.
Magnetic force is the force of attraction or repulsion between two poles of the two magnets. The magnetic force is also appearing between two electrically charged bodies.
Two magnets held apart. Once released, the south pole of one magnet moves toward the north pole of another magnet until the magnets collide.
The graph reflection of kinetic energy of magnet -
When the two magnets are held apart, then the these magnets are at rest and do not possess any kinetic energy.When, the magnets released, then they started to move each other due to the magnetic force of attraction of opposite poles. Therefore, the kinetic energy between two magnets started to increase with the highest speed.Now, as they started to move towards each other, this speed started to reduced and become zero when they meat each other. Here at this point the energy stored in the magnetic field becomes zero.Therefore, graph for the two magnets held apart, kinetic energy is highest when the magnets first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.

An airplane traveling at 201 m/s makes a turn. What is the smallest radius of the circular path (in km) that the pilot can make and keep the centripetal acceleration under 5.0 m/s2 ?
Answer:
the smallest radius of the circular path is 8.1 km
Explanation:
The computation of the smallest radius of the circular path is given below:
Given that
V = Velocity = 201 m/s
a_c = acceleration = 5 m/s^2
radius = ?
As we know that
a_c = V^2 ÷ r
5 = 201^2 ÷ r
r = 201^2 ÷ 5
= 8,080.2 g
= 8.1 km
Hence, the smallest radius of the circular path is 8.1 km
