Answer:
definition of force
Explanation:
It states that "the rate of change in momentum is proprtional to the force applied"
[tex]{ \rm{momentum = mass \times velocity}} \\ [/tex]
• from the law stated:
[tex]{ \rm{ \frac{ \delta momentum}{time} = force}} \\ \\ { \rm{ \frac{mv - mu}{time} = force}} \\ \\ { \rm{ \frac{mass(v - u)}{time} = force}} \\ \\ { \rm{mass \times \frac{(v - u)}{time} = force }}[/tex]
• from first newton equation:
[tex]{ \boxed{ \tt{ \frac{v - u}{t} = acceleration}}} \\ [/tex]
• therefore
[tex]{ \rm{mass \times acceleration = force}} \\ \\ { \boxed{ \rm{force = mass \times acceleration}}}[/tex]

Explanation:
A book is resting on the floor. It has 25 J of energy. A student lifts the book and places it on the top shelf of a bookshelf. The student uses 200 J of energy to lift the book onto the shelf. How much energy does the book have at the top of the shelf?
A.Exactly 25 J
B. About 225 J
C. At least250 J
D.Negative 175 J PLSS QUICK (3 minutes at most) ILL GIVE 70 POINTS AND BRAINLIEST (FOR CORRECT ANSWER)
Answer and Explanation:
A. Exactly 25 J.
This is because the 25 J of energy that is holding down the book will always be the same, unless another force is being applied to hit to either make it heaver for a combined force of J energy, or something is lifting it, which will subtract the force of J of energy whilst moving.

with well labelled diagrams , describe how a bicycle pump works
Explanation:
this is almost similar to how a syringe works. when the pump is drown out, air in the barrel expands and pressure is reduced to below atmospheric pressure. the air from outside the pump is at high pressure so it flows past the leather washer into the barrel. at some point, the higher pressure in the tyre closes for valve.
when the pump handle is pushed in the air is forced into the tyre though the tyre valve which now opens

The velocity of a car increases from +4.0 m/s to +16.0 m/s
in a time period of 4.0 s. What was the average
acceleration?
Answer:
Explanation:
Although we do have an equation for this in terms of one-dimensional motion, it's easy enough just to use the mathematical definition of acceleration:
[tex]a=\frac{v_f-v_0}{t}[/tex] which says, in words, the acceleration of an object is equal to the objects final velocity minus its initial velocity, divided by the change in time. Since everything is given in m and s, our answer will be in m/s/s:
[tex]a=\frac{16.0-4.0}{4.0}[/tex] and
[tex]a=\frac{12.0}{4.0}[/tex] so
a = 3.0 m/s/s

Elements grouped as a column on the periodic table belong to a ______.
Suppose that we replace the aluminum with a mystery metal and repeat the experiment in the video. As in the video, the mass of the metal is the same as that of the water. Room temperature is about 20∘C before the start of the experiment. The water heats up to 40∘C, and the mystery metal heats up to 80∘C. Compared to that of water, the heat capacity of our mystery metal is
Answer: b) one-third as great.
Explanation:
The options include:
a) three times greater.
b) one-third as great.
c) half as great.
d) two times greater.
e) the same.
Since the water heats up to 40°C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (40°C-20°C).= 20°C
Since mystery metal heats up to 80∘C and the room temperature is about 20°C before the start of the experiment, heat absorbed will be: (80°C-20°C).= 60°C.
Therefore, based on the calculation, when compared to that of water, the heat capacity of our mystery metal is (20/60) = 1/3 one-third as great.

Explanation:
_______ is the process which causes magma to form.
Answer:
flux melting
Explanation:
Flux melting is the process that causes magma to form. Flux melting happens when water or carbon dioxide exists added to rock.
What is meant by Flux melting?When rock is exposed to water or carbon dioxide, flux melting occurs. The rock melts at lower temperatures as a result of these substances. This causes magma to form where it had a solid structure before. Around subduction zones, flux melting also happens, much like heat transfer.
Flux melting happens in igneous petrology and volcanology when water and other volatile substances are added to hot solid rock, depressing the solidus. Flux is a material, such as salt, that produces a mixture with a metal oxide that has a low melting point (liquidus) in engineering and metallurgy.

how to do this please
Answer:
1) see the diagram below
2) (b) the length of the wire being tested
Explanation:
1) An ammeter is connected in series with the circuit branch in which you want to measure current. "Conventional current" enters the positive terminal of the ammeter. (You can think of it as a voltmeter across a small resistor. The polarity of the voltage matches the polarity of the current.)
A voltmeter is connected in parallel with the circuit element of interest. Here, you want to measure the voltage across the wire, so the voltmeter is placed in parallel with the wire. The positive terminal of the voltmeter is connected to the end of the circuit element that has the higher (more positive) potential.
__
2) The wording of the problem tells you which variable is independent:
"A varies with B" means the independent variable is B
Here, the independent variable is the length of the wire.

how to calculate acceleration
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Explanation:
hope it help mark me as brill please
Answer:
acceleration equals the change in velocity divided by time
