4. In the Exploration, the sled does not move at all when two equal forces are appliedopposing directions. Explain the reason behind this.
Answers
Answer:
The net force is zero, so the acceleration is zero
Explanation:
Newton's second law states that the acceleration of an object is proportional to the net force applied to it, according to the equation:
(1)
where
is the net force on the object
m is the mass of the object
a is its acceleration
In this problem, we have a sled acted upon two forces, . So the net force on the sled is
(2)
however, we are told that the two forces are equal in magnitude but in opposite directions, so
So, eq.(2) becomes
and so eq.(1) becomes
which means
so the acceleration of the sled is zero, and if the sled was at rest, it will not move.

The equator is the closest part of out planet that is closest to the sun, which means that the continents closest to the equator will in turn be warmer.
What is Equator?
The imaginary line that circles the Earth's center is known as the Equator. It divides the Earth into the Northern and Southern Hemispheres and is located halfway between the North and South Poles.
An equator is a hypothetical line that circles a planet or other celestial body in the centre. At its Equator, the Earth is at its broadest. The circumference of the Earth, measured at its equator, is 40,075 kilometers (24,901 miles).
The equatorial bulge is a phenomena caused by the Earth's diameter being wider in the Equator. A straight line with its endpoints on the circle's edge and a path through its center is used to calculate a circle's diameter.
Therefore, The equator is the closest part of out planet that is closest to the sun, which means that the continents closest to the equator will in turn be warmer.

The question is about Distance and Displacement. Distance, a scalar quantity, represents the total path length traveled between two positions, whereas displacement, a vector quantity, refers to the change in position from the starting to the final point, including direction.
When comparing distance and displacement in the field of science, specifically physics, there are key differences to keep in mind. Distance is a scalar quantity that refers to the total length of the path traveled between two positions. In contrast, displacement is a vector quantity—and thus includes both magnitude and direction—that represents the change in position of an object from its starting point to its end point.
Let's consider an example where you drive from home to school which is 5 km away, then return back home. In this case, the distance you traveled is 10 km because distance simply adds up all the lengths covered. However, the displacement is 0 km because displacement considers the direct path from the starting position to the final position; since you returned home, your initial and final positions are identical, and so the change in position is null.
Therefore, it's important to note that while distance and displacement can sometimes share the same magnitude, they are distinct in that displacement always includes direction. Distance is just a measure of how far an object has travelled, while displacement tells you how far and in which direction it is from the starting point.

Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Formula: °F = (9/5) (°C) + 32 °C is given so I am solving for °F.
°F = (9/5) (25) + 32
=(1.8*25)+ 32
=45+32
=77
Answer= 77°F is equal to 25°C
A. Convert 35°C to °F
B. Convert 80°F to °C
C. Convert 15°C to °F
D. Convert 25°F to °C

completely worked out. The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.
I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.
Write the formula on the wall:
°F = (9/5) °C + 32°
A). Convert 35° C °F = (9/5)(35°) + 32°
(9/5)(35) = 63 °F = 63° + 32°
°F = 95°
____________________________________
B). Convert 80°F to °C
The formula: °F = (9/5) °C + 32°
°F = 80 80 = (9/5)°C + 32
Subtract 32 from each side: 48 = (9/5)°C
Multiply each side by 5 : 240 = (9) C
Now you take over:
_________________________________________
C). Convert 15°C to °F.
The formula: °F = (9/5) °C + 32°
°C = 15 °F = (9/5) 15° + 32
(9/5) (15) = 27
Go ! °F =
