Answer:
4.3825 tons
Explanation:
Hope it helps :)
The one-step conversion you need is (1 ton / 2000 pounds).
It's a fraction that's equal to ' 1 ', because the top and the bottom are equal.
Multiply the 8,765 pounds by it. That won't change the weight. It'll just change the units.
(8,765 pounds) x (1 ton / 2000 pounds) = 4.3825 ton
Why does an iceberg have more HEAT than a cup of coffee.
Explanation:
Although the iceberg has less internal energy per mass, its enormously greater mass gives it a greater total energy than that in the small cup of coffee
Answer:
The hot coffee has a higher temperature, but not a greater internal energy. Although the iceberg has less internal energy per mass, its enormously greater mass gives it a greater total energy than that in the small cup of coffee.

electromagnetic waves can travel through a vacuum. true or false
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. ... This proved that radio waves were a form of light!
Electromagnetic waves can travel through vacuum as well as through mediums. Therefore, the statement is true. The waves which are unable to pass through vacuum is called mechanical waves .
What are electromagnetic waves ?Electromagnetic waves are energetic waves which are associated with a coupled magnetic field and electric field. The electromagnetic spectrum of this waves is the arrangement in the order of increasing frequency or decreasing wavelength.
Radio waves, microwaves, infrared, visible light, UV rays , X- rays and gamma rays are the electromagnetic waves. This order describes the increase in frequency.
Electromagnetic waves can travel trough vacuum. The waves which can pass only through a medium is called mechanical waves. Hence, the statement is true.

The helium-filled balloons below are carrying negative electric charges, as shown. Attach two of the balloons to the hooks below to show what would happen if a red balloon and a blue balloon were brought near each other. Plzz help
Answer:
these are in the hooks the balloons repel each other if the hooks are isolated.
Explanation:
In electrostatics, charges of the same sign repel and of a different sign attract each other.
With this explanation we analyze the situation presented, they indicate that the balloons have a negative taste, so when these are in the hooks the balloons repel each other if the hooks are isolated.
If the hooks are connected to Earth, the poop of the balloons is neutralized, so there is neither attraction nor repulsion.

Find the magnitude of the sum
of these two vectors:
101 m
60.0 °
85.0 m
From the postulation of the parallelogram law of vectors, the resultant vector is 94 m.
What is the resultant vector?The resultant vector refers to that vector that can have the same effect as the two vectors acting together. In this case, we have to use the parallelogram law of vectors.
Thus;
R= √(101)^2 + (85)^2 - 2(101 * 85)cos 60
R = √17426 - 8585
R = 94 m

A person is standing on ice. He throws a snowball with a force of 4 N to the right, while the snowball pushes the
person with a force of 4 N to the left. What is the net force on the person?
A) 4 N, left
B) 8N
Answer:
A) 4n
Explanation:
He throws a snowball with a force of 4 N to the right, while the snowball pushes the person with a force of 4 N to the left. The given scenario is balanced because the same amount of force is acting in both direction.

When the Moon passes through Earth's penumbra, it is a:
a.Solar eclipse
b. Penumbral eclipse
c.Total lunar eclipse

Answer: it is B
Explanation: A penumbral lunar eclipse occurs when the Moon passes through Earth's penumbra. The penumbra causes a subtle dimming of the lunar surface, which is only visible to the naked eye when about 70% of the Moon's diameter has immersed into Earth's penumbra.

You move a 25 N object in 10s with 100 W of power.
How far did you move the object?
Answer:
Distance = 40 meters.
Explanation:
Given the following data;
Force = 25N
Time = 10 seconds
Power = 100 Watt
To find the distance;
First of all, we would determine the work done;
Workdone = power * time
Workdone = 100 * 10
Workdone = 1000 Nm
Next, we use the following formula to find the distance;
Workdone = force * distance
1000 = 25 * distance
Distance = 1000/25
Distance = 40 meters.
A physicist does 100 joules of work on a simple machine that raise a box of bioks through a heigjt of 0.2metres. if the efficiency of the machine is 60%, how much work is converted to thermal energy?
Answer:
the work converted to thermal energy is 40 J.
Explanation:
Given;
work done by the physicist,w = 100 J
height through which the book is raised, h = 0.2 m
efficiency of machine = 60% = 0.6
The useful work done by the machine is calculated as;
useful work = 0.6 x 100 = 60 J
The wasted energy = 100 J - 60 J
The wasted energy = 40 J
The wasted energy by the machine is possibly converted to thermal energy by the frictional part of the machine.
Therefore, the work converted to thermal energy is 40 J.

Listed below are ACTION forces. Tell the REACTION force.
a. Your bottom pushing on your desk seat
b. A bat hitting a baseball
C.
Your finger pressing on your phone screen while texting
Answer:
a. The desk seat will push back on the bottom (reaction force).
b. baseball hit the bat (reaction force)
c. The phone screen presses on your finger (reaction force).
Explanation:
The third law of Isaac Newton explains that, to every force, there is an equal and opposite force. The initial force is called the ACTION FORCE while the opposite force is called the REACTION FORCE. The reaction force for the following action forces in this question are:
- Your bottom pushing on your desk seat (action force)- The desk seat will push back on the bottom (reaction force).
- A bat hitting a baseball (action force) - baseball hit the bat (reaction force)
- Your finger pressing on your phone screen while texting (action force) - The phone screen presses on your finger (reaction force).
