Answer:
I think it's B maybe
Explanation:
If a 1,500 kg car and a 4,000 kg truck were moving at the same speed down a steep hill, what statement is false?
A: The truck will have greater kinetic energy and be more difficult to stop.
B: The car has less mass, and therefore less kinetic energy, when compared to the truck.
C: Both vehicles would have their greatest kinetic energy as they reached the base of the hill.
D: The car's potential energy will be greatest when at its highest speed.
Answer:a
Explanation:because if you have a bigger or heavier truck I can be harder to stop then a car
The car kinetic energy not potential energy is greatest when at its highest speed.
Kinetic Energy:
It is the energy of the object which is due to the motion of object. The formula of kinetic energy is
[tex]\bold {KE = \dfrac 1{2} m v^2}\\[/tex]
Where,
m - mass
v - velocity
The kinetic energy of the object is directly proportional to the mass of the object and square of the velocity of the object.
So, A, B and C are correct statement.
Therefore, the car kinetic energy not potential energy is greatest when at its highest speed.

what would happen if 15 joules of work is done on an object that has 90 N of force applied to it
Answer:
The magnitude of the force is given by F = ma = (10)(5) = 50 N. It acts over a distance of 20 m, in the same direction as the displacement of the object, implying that the total work done by the force is given by W = Fx = (50)(20) = 1000 Joules.

how could you demomstrate a complete and incomplete loop in an electrical circut
Answer:
From the battery, to the component, and back to the battery again. Open circuit is an incomplete loop, where the loop is broken at a particular point and electricity can't flow at all.

Obtain a volume of 12.5 millimeters of liquid in the diagram
Answer:
D remove 1.5 ML of liquid.
Explanation:
Answer:
C. Remove 0.5 mL of liquid.
Explanation:
When measuring the volume of a liquid with a graduated cylinder, you need to measure from the bottom of the meniscus (the curve).
After observation, the volume of the liquid is 13 mL. Therefore, in order to get the desired volume of 12.5 mL, remove 0.5 mL of liquid.

When switching up to high power, you would use all of the following except
A.
the diaphragm
B.
the fine adjustment knob
C.

D.
stage controls
Answer:
COARSE ADJUSTMENT KNOB
Explanation:
Once you use your HIGH POWER OBJECTIVE ONLY use the FINE ADJSUTMENT KNOB! NEVER USE THE COARSE ADJUSTMENT KNOB when ON HIGH POWER. This can cause damage to the slide, the objective lens or both.

I need helppppppp
real answers only please
Answer:
First of all, scientific naming, also known as Biomial Numiclature, is a formal system of naming a specific species or living thing. We all use the scientific naming because we need to work together in most problems as a team and figure out what species an animal or species is.
Explanation:
Just so you know, if we never worked together, our goals would be a lot harder to accomplish. For example, I rn 7 miles yesterday with my mom. If my mom wasn't right there by my side while we were doing it, it would be a lot harder and I would've probably done a lot worse or less mileage.
