List three applications of pressure in our daily lives.
Answer:
1) Skis have a large area to reduce the pressure on the snow. This ensures that the skis do not sink into the snow too far.
2) The pressure under the studs on the soles of football shoes is high enough for them to sink into the ground, which gives extra grip.
3) A vacuum cleaner has a fan inside that creates a low pressure inside the device. Consequently, air and dirt particles are sucked into the device.

Which statement accurately describes the motion of the objects in the ticker tape above?
Both objects are speeding up at a constant rate.
One object speeds up before it slows to a stop.
Both objects speed up before stopping.
One object speeds up at a constant rate until it stops.
Answer:
B
Explanation:
One object speeds up before it slows to a stop.
When reading this type of graph, we know that when the points are far apart, then the object is definitely moving quickly. Also again, we know that when the points are besides each other, then we say that the object is moving slow. When the distance that is between the points are changed, the velocity of the object subsequently changes too, and therefore, we say that the object is accelerated. When there are lots of points in one location, we will see that the object is not moving.
This then translates into that
The object(s) at the top begins to slow, eventually, it increases in its speed, going forward, it slows down again, before it finally halts. The object at the bottom on the other hand, starts fast, before slowing down.
then:
"One object speeds up before it slows to a stop "
When you cook a marshmallow on a metal poker tool over an open flame, energy is transferred. Identify the three different ways thermal energy is transferred in this situation. Be sure to name the specific places or phenomenon in this system where each of the types of thermal energy transfer is occurring and the direction the energy is being transferred (from what to what).
Answer:
The three ways thermal energy is transferred are;
1) Conduction
2) Convection
3) Radiation
Explanation:
1) The conduction of the heat from the open flame to the marshmallow is through the direct contact of the flame with the marshmallow, such that the flame the region of the combustion reaction, that produces light and heat touches the marshmallow
2) The convection process is the transfer of heat from the rising heated combustion products, as well as the heated air that rises from the flame
3) The radiation heat transfer is the transfer of the heat from the fire to the marshmallows directly by the heat the moves in the form of electromagnetic waves at temperatures above 1000 K, without the need for a medium, such that the marshmallow can be heated by the heat coming from side of the flame.

An Alaskan rescue plane traveling 46 m/s drops a package of emergency rations from a height of 101 m to a stranded party of explorers. The acceleration of gravity is 9.8 m/s^2. Where does the package strike the ground relative to the point directly below where it was released? Answer in units of m.
Answer:
The package strikes 207 m at the ground relative to the point.
Explanation:
Given that,
Speed = 46 m/s
Height = 101 m
Acceleration = 9.8 m/s²
We need to calculate the time
Using equation of motion
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
Put the value in the equation
[tex]101=0+\dfrac{1}{2}\times9.8\times t^2[/tex]
[tex]t=\sqrt{\dfrac{2\times101}{9.8}}[/tex]
[tex]t=4.5\ sec[/tex]
We need to calculate the distance where the package strikes
Using formula of distance
[tex]x=vt[/tex]
Put the value into the formula
[tex]x=46\times4.5[/tex]
[tex]x=207\ m[/tex]
Hence, The package strikes 207 m at the ground relative to the point.

The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero
a = 0m/s²
The constant speed is 6m/s
v = 6m/s
So, force to keep it moving with this constant speed can be calculated using Newton second law of motion
F = ma
F = m × 0
F = 0N
So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
A fixed particle with charge –8.8 nC and a second particle with charge –4.3 nC, respectively, are initially separated by a distance of 0.11 m. They are released and the second particle moves 0.030 m. A) What is the change in electric potential energy? B) Did the second particle move toward or away from the source charge?
Answer:
(a). The change in electric potential energy is 8.3 μJ.
(b). The second particle moves away from the source charge.
Explanation:
Given that,
Charge of first particle = -8.8 nC
Charge of second particle = -4.3 nC
Distance = 0.11 m
They are released and the second particle moves 0.030 m,
(a). We need to calculate the change in electric potential energy
Using formula of potential energy
[tex]U=\dfrac{Kq_{1}q_{2}}{d}[/tex]
Change in potential energy
[tex]\Delta U=\dfrac{kq_{1}q_{2}}{d_{2}}-\dfrac{Kq_{1}q_{2}}{d_{1}}[/tex]
Put the value into the formula
[tex]U=\dfrac{9\times10^{9}\times(8.8\times10^{-9}\times4.3\times10^{-9})}{0.030}-\dfrac{9\times10^{9}\times(8.8\times10^{-9}\times4.3\times10^{-9})}{0.11}[/tex]
[tex]\Delta U=0.000008256\ J[/tex]
[tex]\Delta U=8.3\ \mu J[/tex]
(B). We need to find the second particle move toward or away from the source charge
We know that,
Both charges are same, so the second particle will be repul from the source charge.
So, The second particle moves away from the source charge.
Hence, (a). The change in electric potential energy is 8.3 μJ.
(b). The second particle moves away from the source charge.
