No and yes
Explanation:
Yes technically you are time traveling.
But not in the way like the movies or whatever when they go to 1956 or whatever.
You are time traveling because you are going from 2:30 to 12:00. And you are traveling :|

Brainliest whoever answers first!!! and right!!! Identify the situations that have an unbalanced force. Check all that apply. a weight speeds up as it falls through the air a garbage can is at rest on the ground a hockey puck moves in a straight line at a constant speed a bumper car hit by another car moves off at an angle a balloon flies across the room when the air is released
Answers
Answer:
its A,D,E
Explanation:
I got 2 right one of them wrong
Answer:
A baseball speeds up as it falls through the air.
Yes. Forces on the balloon are unbalanced.
The balloon is speeding up, so we know that the downward force
of gravity is stronger than the upward force of air resistance.
A soccer ball is at rest on the ground.
No. The ball is not accelerating, so we know that the forces on it
are balanced.
The downward force of gravity on the ball and the upward force
of the ground are equal.
An ice skater glides in a straight line at a constant speed.
No. The skater's speed and direction are not changing, so he is not
accelerating. That tells us that the forces on him are balanced.
A bumper car hit by another car moves off at an angle.
Yes. The direction in which the car was moving changed.
That's acceleration, so we know that the forces on it are unbalanced,
at least at the moment of impact.
A balloon flies across the room when the air is released.
Yes. The balloon was not moving. But when the little nozzle was
opened, it started to zip around the room. So its speed changed.
And, as it goes bloozing around the room, its direction keeps changing too.
There's a whole lot of acceleration going on, so we know the forces on it
are unbalanced.

Which of the following is not apart of the Particle Theory of Matter? *
A. Atoms are always in motion
B. The motion of atoms increase with temperature
C. Atoms attract each other
D. Atoms do not have empty spaces between them
Answers
Answer:
D. Atoms do not have empty spaces between them
Explanation:
That atoms do not have empty spaces between them is not part of the particle theory of matter.
Here are some of the postulates of the theory;
A gas is composed of a large number of identical molecules moving at different speeds. The space occupied by gas molecules is negligible compared to the volume of space they occupy. The temperature of a gas is a function of their average kinetic energy.what is the acceleration of a softball if it has a mass of 0.50kg and hits the catcher’s glove with a force of 25 N

A women weighs 857 N. What is her mass?
Answers
Answer:
women based on height usually should way about 200 pounds which included muscle.
Explanation:
Force of gravity is another way of saying weight. We are given her weight, and we also know that gravity is 9.8m/s^2; therefore, you can set up your algebraic equation like this: 857 = m x 9.8. Now, you have to divide 857 by 9.8 to get mass by itself. 857/9.8 is approximately 87.4489 kilograms.
So your answer is 87.4489 kg!
The full answer is 87.44897959, but in physics, we usually just like to use the four numbers after the decimal place.

connecting wires, a battery, an ammeter, and a magnetic core wrapped in
wire?
A. Cover the ammeter with the same insulation that is on the wires.
B. Remove the wire that is wrapped around the magnetic core
material.
C. Wrap the battery with insulated wire.
D. Remove the insulation from the ends of the connecting wires.
SUBMIT
Answers
Answer:
The answer should be
D. Remove the insulation from the ends of the connecting wires.
Explanation:
The exact letter may not be D for everyone but the answer is
Remove the insulation from the ends of the connecting wires.
The action that you must take before starting to make an electromagnet out of connecting wires, a battery, an ammeter, and a magnetic core wrapped in wire is to "remove the insulation from the ends of the connecting wires". Hence, Option D is the correct answer.
What is an electromagnet?Electromagnet, can be described as the device which consists of a core of magnetic material surrounded by a coil through and it allows the electric current to pass so as to magnetize the core.
It should be noted that the electromagnet can be made to function in a case where there is controllable magnets are required, which can be contrivances in which the magnetic flux is to be varied, hence in the case above Removal of the insulation from the ends of the connecting wires will be the best action since the you are making an electromagnet out of connecting wires, as well as battery, an ammeter.
Therefore, option D is the correct answer.

A science class breaks into four groups and tests the pH of the soil surrounding the school. Each group goes to an area that is three meters squared (3m2) in size and tests the soil four different times within that square. The data collected is then placed into a table for everyone to see as shown below.
Four students draw the following conclusions from the data
Student 1. Group D's data should be discarded because it is not similar enough to the other groups' data
Student 2: There must be something near the parking lot that causes the pH of the soul to be higher and the class should design a new experiment to determine whether
Student 3. There are definitely more magnesium ions in the soil near the parking lot, and that is why the pH of the soil is higher there
Student 4. The pH of the soil in the ball field should be measured again because no two readings were identical

b. Joints allow the roadway to expand and

c. Joints allow the roadway to expand and contract as cars put force on the bridge
d. Joints allow the bridge to be built in smaller, easier to assemble pieces.
Answers
Answer:
c. Joints allow the roadway to expand and contract as cars put force on the bridge
Explanation:
The reasons why joints are allowed on roadway is to accommodate the contraction and expansion of the road as cars put force on them.
Most materials used in making roadways are susceptible to expansion and contraction. When a measure of force is applied their length either increases or decreases depending on the type of force. To accommodate these changes, joints are placed in roadwaysWhat is the force of a box with a mass of 50 Kg being accelerated with a force of 9.8 m/s27

A 15.0kg object is resting on the earth. What is the mass and weight of the object?
Answers
Answer:
The mass of the object is 15.0 kg
The weight of the object is 147.15 N
Explanation:
The mass of the object is the quantity of matter contained in the object or the measure of the its property of inertia.
The mass is constant through out the universe
The mass of the object is given as 15.0 kg
The weight of the object is the force of attraction of the Earth on the object
The weight is dependent on the interacting objects.
The weight of the object = The mass of the object × Acceleration due to gravity
Where;
The acceleration due to gravity, g = 9.81 m/s²
∴ The weight of the object = 15.0 kg × 9.81 m/s²= 147.15 N
The weight of the object = 147.15 N
