If the velocity of particle is high then they will collide with each other with a greater force because their momentum will be high
What is force?force is a push or pull on a body .
What is momentum?Momentum is the product of mass and velocity,
More the velocity, higher will be the momentum.
since force is directly proportional to rate of change of momentum
F = Δp/Δt
so on when bodies having higher velocities collide their rate of change of momentum is higher hence more will be the force

A group of friends are going bowling. They discuss how ball weight and speed can change the amount of
kinetic energy transferred to the pins.
They can use a 6 pound, 10 pound or 12 pound ball.
They can roll the ball at 10 miles per hour (beginner), 14 miles per hour (intermediate) or 18 miles per hour (professional) speed.
A. Describe a strategy that they could use to transfer the greatest amount of kinetic energy to the pins.
B. Explain the relationship between kinetic energy and strategy that you chose in part A.
C. Draw a model that demonstrates the energy transfers that occurred in the system.
Answer:
A. you would want to use the 12 ound ball and the 18 mph speed in order to transfer the most kinetic energy
B. KE= 1/2 MV^2 so you would want to maximize both your Mass(weight of the ball) and Velocity(speed of the roll) in order to achive the greatest KE.

a cycle lasts for 8 seconds. what is the frequency
This frequency definition leads us to the simplest frequency formula: f = 1 / T . f denotes frequency and T stands for the time it takes to complete one wave cycle measured in seconds. The SI frequency unit is Hertz (Hz), which equals 1/s (one cycle per second)

A plane flies along a straight line path after taking off, and it ends up 90.0 km farther east and 200.0 km farther north, relative to where it started. In what direction did it fly on the straight line path?
27° north of east
45 ° north of east
24° north of east
66° north of east
Answer:
24° north of east
Explanation:
tan(x)=90/200 ie x=arctan(90/200)=24°
So the plane took off 24° east.

force of 7 N acts on an object.
The displacement is, say 8 m, in
the direction of the force
(Fig. 11.3). Let us take it that the
force acts on the object through
the displacement. What is the
work done in this case?
Explanation:
Given
Force (F) = 7 N
Displacement (d) = 8 m
work done (W) = ?
We know that
W = F * d
= 7 * 8
= 56 J
The work done in this case is 56 Joule.
A plate has an area of 1m square. It slide down an incline plane , having an angle of inclined 60° to horizontal, which a velocity of 0.75m/s. The thickness of oil film between the plate and the plate is 2mm. Find the viscosity of the fluid if the weight of the plate is 90N
Answer:
[tex]\mu =0.169704 Ns/m^2[/tex]
Explanation:
From the question we are told that
Area of plate[tex]a=1m^2[/tex]
Angle of inclination [tex]\theta=60 \textdegree[/tex]
Velocity [tex]v=0.75m/s[/tex]
Thickness of oil [tex]t=2mm[/tex]
Weight of plate [tex]w=90N[/tex]
Generally the equation for shear force is mathematically given by
[tex]F=mgsin45 \textdegree[/tex]
[tex]F=90sin45 \textdegree[/tex]
[tex]F=63.639N[/tex]
[tex]F=\mu* \frac{v}{t}[/tex]
[tex]F=\mu* \frac{0.75}{2*10^-^3}[/tex]
[tex]\mu* \frac{0.75}{2*10^-^3}=63.639N[/tex]
[tex]\mu =\frac{63.639}{375}[/tex]
Therefore viscosity is given by
[tex]\mu =0.169704 Ns/m^2[/tex]

what is the approximate increase in thermal energy in joules when the temperature of 15 grams of water is raised from 20° to 35° C. the specific heat of water is 4.19 j/g degrees Celsius
Answer:
942.75J
Explanation:
Change in thermal energy is equal to the mass of the given substance times the specific heat capacity times the temperature change.
We've already been given the specific heat capacity, the mass as well as the initial and final temperatures.
So change in temperature will be 35° - 20° = 15°
Thermal energy change = 15 × 15 × 4.19
The final answer is 942.75J
Hope that helped.

A 55 kg skier is at the top of a slope. The vertical distance between start and finish is 10m. (a) What is her Potential Energy? (b) How fast is she moving at the bottom of the hill?
Explanation:
Given that,
Mass of a skier, m = 55 kg
The vertical distance between start and finish is 10 m.
(a) The potential energy of a skier is given by :
[tex]E=mgh\\\\E=55\times 9.8\times 10\\\\=5390\ J[/tex]
(b) When she reaches the bottom of the hill, the potential energy is converted to kinetic energy. So,
[tex]5390=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2\times 5390}{55}} \\\\v=14\ m/s[/tex]
Hence, her potential energy is 5390 J and at the bottom of the hill she is moving with a speed of 14 m/s.

A person’s blood type depends on the type of protein marker, called an , found on the cell membranes of the red blood cells.
A person’s blood type depends on the type of protein marker, called an Antigen, found on the cell membranes of the red blood cell.
What is antigen?A molecule known as an antigen is one that triggers the formation of an antibody and the immune system's response.
Large protein molecules known as antigens are found on the surface of pathogens like bacteria, fungi, viruses, and other foreign substances. When these dangerous substances enter the body, the body's immune system reacts by producing antibodies.
The ABO system distinguishes 4 major blood types:
Blood group O - has no antigens, but both anti-A and anti-B antibodies in the plasma. Blood group AB - has both A and B antigens, but no antibodies.Blood group A - has A antigens on the red blood cells with anti-B antibodies in the plasma. Blood group B - has B antigens with anti-A antibodies in the plasma.Learn more about antigen here:

The energy the Sun gives off is caused by nuclear reactions in its core. The extreme pressure from the weight of the gases that make up the Sun raises the temperature of the core enough for the nuclear reactions to take place. Which law best describes this behavior of gases in the Sun?
Answer:
The law which describes the behavior of gases in the Sun is Gay-Lussac's Law
Explanation:
The states that the extremely high pressure of the gases in the Sun produces extremely high temperature;
Therefore, the relationship between the pressure, 'P', of the gas and the temperature, 'T', of the gas is a direct relationship, which can be expressed mathematically as follows;
P ∝ T
The law which best describes the behavior of gases in the Sun is Gay-Lussac's Law, which states that the pressure of a given volume of gas varies directly as the absolute temperature of the gas, as follows;
P = K·T
∴ P/T = K (Constant)
[tex]\therefore \dfrac{P_1}{T_1} = \dfrac{P_2}{T_2}[/tex]

Gravitational force
Solution
Newton's Gravity Law:
[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]
with F = gravitational force,
G = gravitational constant,
m1, m2 = mass of object,
r = distance between two objects.

Geologists use tools other than the law of superposition to help them with relative dating. Which statements describe those tools? Check all that apply.
Answer: Cross-cutting features are always younger than the surrounding rock.
When material erodes before sediment is deposited on it, a geologic gap results.
Explanation:
The options include:
1. An unconformity is created when lava pours out on Earth’s surface.
2. Faults are the result of volcanic activity.
3. Intrusions and extrusions are sedimentary formations.
4. Cross-cutting features are always younger than the surrounding rock.
5. When material erodes before sediment is deposited on it, a geologic gap results.
The law of superposition simply states that when there is a layers of rocks, we would see that the younger layers will lie and be on top of the layers that are older.
Other tools that can help scientist with relative dating are:
• Cross-cutting features are always younger than the surrounding rock.
• When material erodes before sediment is deposited on it, a geologic gap results.
