wite a paragraph explaining the difference between things that have matter and things that don't have matter.
Answer: Matter is how much space or opacity an object takes up. In short anything that take up space. Things like balls, trees, and even people are all made of matter. Mass is how much matter a object has. Air also has mass also, even though we can't see it. Things like cars, buildings, even planets have mass.

Prove that s=ut+½at²
Explanation:
Distance travelled = Area under the line
= ut + ½ (v-u)t
Acceleration (a) = (v-u)/t and so (v-u) = at
Therefore,
Distance travelled (s) = ut + ½ (v-u)t = ut + ½ (at)t = ut + ½ at²
Thus,proved.

A rock is thrown straight up from the edge of a cliff. The rock reaches the maximum height of 15 m above the edge and then falls down to the bottom of the cliff 35 m below the cliff. What is the traveled distance of the rock?
A. 30 m B. 35 m C. 50 m D. 65 m
Answer:
The distance travelled by the rock is 65m
The rock is thrown 15 m up from the edge of the cliff and it have to travel 15 m down to reach the cliff and go to bottom of the cliff by 35 m. Thus, the total distance travelled by the rock is 65 m.
What is distance?Distance is a physical quantity used to measure how far an object is travelling. It is a scalar quantity and is characterised by magnitude only. Distance travelled is sometimes substituted with displacement. Both have the units in cm, m, feet, kilometer etc.
Distance in physics is the product of the speed of a moving body and the time taken complete the travel.
Distance = speed × time.
It is given that, the rock is thrown straight up from the edge of a cliff and it reaches upto 15 m. Then it have to return back this 15 m down to reach the edge. From there it goes 35 m below.
Thus, total distance = 15 + 15 + 35 = 65 m.
Therefore, the total distance travelled by the rock is 65 m.

g A high-energy photon turns into and electron and a positron. (A positron has exactly the same mass as the electron, but opposite charge.) What is the longest wavelength that the photon can have for this process to occur
Answer:
2 m = E / c^2 where m is mass of electron
E = h v where v is the frequency ( nu) of the incident photon
E = h c / y where y is the incident wavelength (lambda)
2 m = h / (c y)
y = h / (2 m c) wavelength required
y = 6.62 * 10E-34 / (2 * 9.1 * 10E-31 * 3 * 10E8) m
y = 3.31 / 27.3 E-11 m

Questions: 1. Do these resistors satisfy Ohm ’ s law? Explain your answer. — All resistors satisfy Ohm's law unless the current through the resistor is more than the ca-pacity of the resistor which might lead to meltdown of the material due to heating.2. Is an ammeter connected in series or parallel with a circuit component? Explain. — An ammeter must always connect in series. As the ammeter measures current in a circuit/loop it must be connected along with a circuit element.3. Is a voltmeter connected in series or parallel with a circuit component? Explain. — A Voltmeter measure voltage across a circuit element, hence it must be connected paral-lel to the element that we have to measure voltage.

An amusement park designer wants his swing to have a centripetal acceleration of 24 m/s2. If the velocity of the swing is 11 m/s, how long should the chain on the swing be?
A. 6.5 m
B. 5.5 m
C. 5.0 m
D. 6.0 m
Answer:
radius is C: 5.0 m
Explanation:
formular for centripetal acceleration:
[tex]a = \frac{ {V}^{2} }{r} [/tex]
a is acceleration
V is velocity
r is radius
[tex]24 = \frac{ {11}^{2} }{r} \\ \\ r = \frac{ {11}^{2} }{24} \\ \\ r = 5.0 \: m[/tex]
This length is approximate.
==========================================================
Explanation:
The centripetal acceleration formula we use is
a = (v^2)/r
where v is the linear velocity and r is the radius. The swing moves in a circular path, so the chain acts as the radius. If we can find the radius, then we have found the chain length. The goal is to find r when a = 24 and v = 11
So we have...
a = (v^2)/r
24 = (11^2)/r
24 = 121/r
24r = 121
r = 121/24
r = 5.041667 approximately
r = 5.0 meters when rounding to the nearest tenth
The chain should be approximately 5.0 meters.
A lad, waiting for his friend walks in the sidewalk, in front of her house, from the front door, first, he moves towards the Positive x-axis, 5 m, then goes back, 6 m. What is his total displacement from his original position? Displacement is a vector quantity whilst, distance is a scalar quantity.
His total displacement from his original position is -1 m
We know that total displacement of an object from a position x to a position x', d = final position - initial position.
d = x' - x
If we assume the lad's initial position in front of her house is x = 0 m. The lad then moves towards the positive x-axis, 5 m. He then ends up at x' = 5 m. He then finally goes back 6 m.
Since displacement = final position - initial position, and his displacement is d' = -6 m (since he moves in the negative x - direction or moves back) from his initial position of x' = 5 m.
His final position, x" after moving back 6 m is gotten from
x" - x' = -6 m
x" = -6 + x'
x" = -6 + 5
x" = -1 m
Thus, his total displacement from his original position is
d = final position - initial position
d = x" - x
d = -1 m - 0 m
d = -1 m
So, his total displacement from his original position is -1 m
