Answer:
Trabajo realizado = 600 Nm
Explanation:
Dados los siguientes datos;
Fuerza = 200 Newton
Distancia = 3 metros
Para encontrar el trabajo realizado; Trabajo realizado = fuerza * distancia
Sustituyendo en la ecuación, tenemos; Trabajo realizado = 200 * 3
Trabajo realizado = 600 Nm

Which has greater density- 1 kg of water or 10kg of water?
Answer:
I believe that it will be 10kg of water
Explanation:
Because a measure of the amount of information on a storage medium (tape or disk). For magnetic tape it is the amount of information recorded per unit length of tape (bits per inch or millimeter); for a disk, a fixed number of bits per sector, sectors per track, and tracks per disk.
The density in both the case will be equal, just the difference will be in the volume they occupy.
What is density?In practice, density is the weight of a substance per unit volume. Water has a density of about 1 gram per milliliter, but this varies depending on temperature and whether or not substances are dissolved in it. Because ice is less dense than liquid water, it floats in your glass.
This allows many aquatic organisms to survive the winter. If ice were more dense than water, it would continue to freeze and sink until the entire lake was frozen.
Any amount of water has the same density. Whereas one gram of water has a volume of one milliliter, ten grams have a volume of ten milliliters.
Thus, the density will be same.

What is the velocity of a 24 kg object with 108 kg m/s of momentum?
A) 3 m/s
B) 4.5 m/s
C) 6 m/s
D) 84 m/s
Answer:
The velocity of the object is 4.5 m/s
Explanation:
Momentum is equal to mass times velocity. We can rearrange that relationship to say that velocity is equal to momentum divided by mass. With that we can say:
v = 108 kg m/s / 24kg
v = (108 / 24) m/s
v = 4.5 m/s
A 780 kg vehicle accelerates at 4 m/s2. How much force is the car generating?
Explanation:
Given
mass (m) = 780 kg
acceleration (a) = 4 m/s²
Force (F) = ?
We know
F = m * a
= 780 * 4
= 3120 Newton
The car is generating 3120 Newton force.

Your student desk has been in the room for many hours, it is at thermal equilibrium with the room?
Which part of your desk is colder: the wood or the metal? Why?
Answer:
metal because A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they're good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. Thermal insulators like plastic and wood don't transfer heat as easily.

Calculating net force
Answer:
0N.
Explanation:
Net force is the sum total of forces acting on an object.
The Fn which is the net force is
450+ (-250) + (-600)+ 600+ 0 + 250 + (-450)
= 450-250+(-600)+ 600+0+250-450
= 0N
The net force is 0

What happens as a bungee jumper gets closer to Earth's surface?
A. Gravity decreases
B. His mass increases
C. Air resistance decreases
D. His velocity increases
Answer:
Velocity increases
Explanation:
Gravity is constant, except when discussing "apparent weight"
Mass is constant here
Air resistance would actually increase
Velocity DOES increase, because Earth is pulling the jumper downwards with an unbalanced force. The unbalanced force creates acceleration (-9.81 m/s^2), which means his velocity is increasing constantly.
