Answer:
The sled will slow down in speed
Explanation:
According to Newton's first law of motion, a body will continue to be at rest or uniform motion unless acted upon by an external force.
In this situation, once the connecting rope between the sled and the dogs breaks, the motion of the sled will reduce because it is no longer connected to the dog that is providing the motion, hence the source of motion is no longer connected to the sled

Which change would reverse the direction of the electric current generated through electromagnetic induction?
moving the magnet slower
using more loops of wire in the solenoid
using the opposite pole of the magnet
using a weaker magnet
Using the opposite pole of the magnet would reverse the direction of the electric current generated through electromagnetic induction.
What takes place while the current is reversed in an electromagnet?Whilst you opposite the path of the contemporary flowing within the cord, the north and south poles also are reversed. When you reverse the contemporary once more, the north and south poles reverse again. In fact, on every occasion the modern is reversed, the north and south poles will trade places.
Which alternate will reverse the route of the electric modern-day generated thru electromagnetic induction?A magnet and a coil of wire can be used to provide an electric-powered modern-day. A voltage is produced while a magnet moves into a coil of cord. This procedure is known as electromagnetic induction. The direction of the caused voltage is reversed while the magnet is moved out of the coil once more.

A wire of resistance 27 ohm is folded 3 times find its new resistance
Answer:
New resistance = 243 ohm
Explanation:
Given:
Current resistance = 27 ohm
Computation:
The wire is extended to three times its initial size, and its cross-section is therefore shortened to one-third of how it used to be. We found the current resistance to be 3x3= 9 times
So,
New resistance = 27 x 9
New resistance = 243 ohm

23. Quantities that can be described completely by their magnitude or size are called vector quantities. (5 points)
True
False
Answer:
False
Explanation:
Vector has a magnitude and direction.
A scalar is just a magnitude or size.
The answer is false.
What is scalar and vector quantities?
Scalar quantity:
The scalar quantity will have only the magnitude ( how much or size).These scalar quantity are one dimensional. These can be represented only by calculating the changes in the magnitude. If we need to change the value of scalar we are not able to change because it has no directions to determine the values of the quantity.If we have to perform any kind of mathematical operation, i.e., scalar with scalar we get scalar but when we did the mathematical operation with the scalar and vector then we get the answer is in the vector. some of the scalar quantities are as follows:Speed, Mass, length, distance, power, energy, work.
Vector quantity:
The vector quantity will have both magnitude and direction.The vector quantities are one dimensional, 2 dimensional, else can also be 3 dimensional.Vector quantities can be changed or determined both by the magnitude and direction. If we change the adjacent angles then there changes will occur in the direction.We can perform any kind of mathematical operation.Some of the vector quantities are: Displacement, velocity, acceleration, force, weight, friction, momentum.Hence, Option B is the correct answer.

A 10 kg ball is rolled to the top of a hill 37 m high using 4000 J of work. How much energy was lost due to heat?
Answer:
370.3J
Explanation:
A 10 kg ball is rolled to the top of a hill 37 m high using 4000 J of work. How much energy was lost due to heat?
Step one:
given data
mass m= 10kg
height of the hill= 37m
work done= 4000J
Step two:
The quantity of energy loss due to heat is the same as the difference in the potential energy possed by the mass and the work done
PE= mgh
PE=10*9.81*37
PE= 3629.7J
Hence the energy loss is
= 4000-3629.7
=370.3J

Explanation:
A block moves along a table at a constant velocity and then rolls off the edge of the table. The forces that should be included in a free body diagram for the ball as it falls to the ground are:
normal force from table
friction force from table
gravity
force of fall
Answer:
Gravity
Explanation:
When the ball is falling to the ground, there is only one force- gravity. In some cases, there may be air resistance, but that seems to be neglected here.
Normal force:
Cannot be included. Normal force is only applicable when object is on a surface, and it acts perpendicular to the surface. Since the ball is falling, there is no surface, and therefore no normal force. This question gives you unnecessary information, designed to trick you. Please remember when normal force is applicable.
Friction force:
Also only applicable when object is moving, and is on the table. Friction only applies when there is an applied force. There is no applied force when the ball is falling, so therefore no friction force.
Force of fall:
First of all, what is this? There is nothing called force of fall.
Gravity:
This is the only one that applies. Just draw a vector arrow from the bottom of the ball and label it mg (acceleration due to gravity).

An airplane flies for 1.25 hours with a constant speed of 1080 km/hr and then for another 2.5 hours with a constant speed of 984 km/hr. How far (what distance) did it go?
Answer:
The airplane went 3810 km
Explanation:
The Distance at Constant Speed
The speed is defined as the rate of change of the distance:
[tex]\displaystyle v=\frac{d}{t}[/tex]
The distance is calculated by solving for d:
d = vt
The airplane first flies at v=1080 Km/h for t=1.25 hours. The first distance is:
d1 = 1080 Km/h * 1.25 h = 1350 Km
Then it flies at v=984 Km/h for t=2.5 hours. The second distance is:
d2 = 984 Km/h * 2.5 h = 2460 Km
The total distance was 1350 + 2460 = 3810 km.
The airplane went 3810 km
Why do electrons stay around the nucleus of an atom?
Answer:
the nucleus of the atom is positively charged and the electrons are negatively charged, they are attracted to each other...
Answer:
There are 2 different types of neutrons. Negative and positive. They are both fighting over the atom. The atom doesn't know who to pick! The happy one? Or the emo one? They are both staying close because they don't want to lose this fight. (Actual answer below)
Explanation:
When there are too many protons, some of the outer protons are loosely bound and more free to react with the electron. But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.

Answer:
Same reading.
Explanation:
Assume that after the string breaks the ball falls through the liquid with constant speed. If the mass of the bucket and the liquid is 1.20 kg, and the mass of the ball is 0.150 kg,
A.) Before the string break, the total weight = weight of the can + weight of the water.
According to Archimedes' Principle which state that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.” Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it
B.) After the string break.
The scale will have the same reading as before the string break.

When the motion energy of an object changes, energy is being transferred. How do you know that's true?
Answer:
Explanation:
When objects collide, energy can be transferred from one object to another, thereby changing their motion. In such collisions, some energy is typically also transferred to the surrounding air; as a result, the air gets heated and sound is produced.
