Answer:
option f) all of the above
We will see that all of the given options would increase the momentum, so the correct option is f "all of the above"
How to increase the momentum?
Momentum is defined as the amount of motion, and it is given by:
P = m*v
Where m is the mass of the object and v is the velocity.
We can't change the mass of the golf ball, but we can change the velocity, and to do it, we need to increase the acceleration that we apply to the ball.
To increase the acceleration we can:
follow through when hitting the ball (the force is applied for more time, so the acceleration is larger).increase the force acting on it (it directly increases the acceleration).increase the time of contact with the ball (similar to the first option).swing as hard as possible (similar to the second option).Then all the options are correct, which means that the correct option is f.

Which can make 4 covalent bonds? Carbon, Silicon, or both?
Answer:
I would say both
Explanation:
Each silicon atom has four valence electrons which are shared, forming covalent bonds with the four surrounding Si atoms.
Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom (Figure 1).

describe the steps that occurs in the process of fission
Answer:
--In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. -- In the second step, one of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.
OR
Nuclear fission begins when a neutron hits the nucleus of an atom. The nucleus splits in two and releases thermal energy and releases more neutrons. The neutrons hits the nuclei of more atoms, splitting them and releasing more energy and neutrons.

how are electromagnetic waves produced
Answer:
Electromagnetic waves are created by oscillating charges (which radiate whenever accelerated) and have the same frequency as the oscillation. Since the electric and magnetic fields in most electromagnetic waves are perpendicular to the direction in which the wave moves, it is ordinarily a transverse wave.
Answer: Electromagnetic waves are the combination of electric and magnetic field waves produced by moving charges.
The creation of all electromagnetic waves begins with a charged particle. This charged particle creates an electric field (which can exert a force on other nearby charged particles). When it accelerates as part of an oscillatory motion, the charged particle creates ripples, or oscillations, in its electric field, and also produces a magnetic field (as predicted by Maxwell’s equations).
Once in motion, the electric and magnetic fields created by a charged particle are self-perpetuating—time-dependent changes in one field (electric or magnetic) produce the other. Both electric and magnetic fields in an electromagnetic wave will fluctuate in time, one causing the other to change.
Electromagnetic waves (photons) are produced anytime a charged particle experiences a change in velocity.. The electromagnetic wave (radiation) that is produced when the charge particle changes it’s velocity is how energy is conserved. This energy is light.

Explanation:
Use Gauss's Law to find the electric field produced by an infinite plane of uniformly distributed charge Q, with charge density σ. Draw the appropriate Gaussian Surface
Answer:
Explanation:
Consider an endless sheet of uniform charge thickness per unit area [tex]\sigma[/tex]
For a boundless sheet of charge, the electric field will be opposite to the surface. In this way, just the closures of a round and hollow Gaussian surface will add to the electric transition. For this situation, around and hollow Gaussian surface opposite to the charge sheet is utilized. The subsequent field is a large portion of that of a conductor at harmony with this surface charge thickness.
By balance, we expect the electric field on one or the other side of a plane to be an element of x just to be guided typical to the plane and to point away from/towards the plane contingent upon whether, [tex]\sigma[/tex] is positive/negative.
According to the law;
[tex]2EA = \dfrac{q_{enc}}{\varepsilon_o}[/tex]
[tex]where; \ q_{enc} = total \ enclosed charge = \sigma A \\ \\ thus; \\ \\ 2EA = \dfrac{\sigma A}{\varepsilon_o} \\ \\ E = \dfrac{\sigma}{2 \varepsilon _o}[/tex]

Explanation:
Answer:
Explanation: (Momentum is mass * velocity. Its units, in the SI system are kilogram meter per second) What is Inertia?
In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops. The word momentum is also used as part of everyday speech, and is one of the very few physics concept whose metaphorical definition is the same as its actual one.

What is the speed of a 180 g ball if its kinetic energy is 100 J?
Answer:
Velocity, V = 33.33 m/s
Explanation:
Given the following data;
Mass = 180grams to kilograms = 180/1000 = 0.18 kg
Kinetic energy = 100J
To find the speed;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
100 = ½*0.18*V²
Cross-multiplying, we have;
200 = 0.18*V²
V² = 200/0.18
V² = 1111.11
Taking the square root of both sides, we have;
Velocity, V = 33.33 m/s

Question: A pinball machine's plunger has a spring constant of 22
N/m and is compressed by 0.04 m to start a 0.006 kg pinball.
1. What is the elastic potential energy before the ball is released?
2. What is the kinetic energy of the pinball the instant it leaves the
spring?
3. What is the speed of the pinball the instant it leaves the spring?
4. If the pinball is moving at 1.3 m/s as it is deflected horizontally
across the top of the pinball machine, how much higher above the
ground is this part of its path when compared to its starting
position?

Answer:
1. The elastic potential energy is 0.0176 Joules
2. The kinetic energy of the pinball the instant it leaves the spring is 0.0176 Joules
3. The speed of the pinball the instant it leaves the spring is approximately 2.42212 m/s
4. The height of the part where the pinball is located on the machine above the ground is approximately 0.213 meters
Explanation:
The spring constant of the pinball machine's plunger, k = 22 N/m
The amount by which the pinball machine's plunger is compressed, x = 0.04 m
The mass of the pinball ball, m = 0.006 kg
1. The elastic potential energy, P.E. = 1/2·k·x²
By substitution, we get;
P.E. = 1/2 × 22 N/m × (0.04 m)² = 0.0176 J
The elastic potential energy, P.E. = 0.0176 J
2. At the instant the pinball leaves the spring, the plunger and therefore the force of the plunger no longer acts on the pinball
Since there are no external forces acting on the pinball to increase the speed of the pinball after it leaves the spring, the velocity reached is its maximum velocity, and therefore, the kinetic energy, K.E. is the maximum kinetic energy which by the conservation of energy, is equal to the initial potential energy
Therefore;
K.E. = P.E. = 0.0176 J
The kinetic energy of the pinball the instant it leaves the spring, K.E.= 0.0176 J
3. The kinetic energy, K.E., is given by the following formula;
K.E. = 1/2·m·v²
Where;
v = The speed or velocity of the object having kinetic energy K.E.
Therefore, from K.E. = 0.0176 J, and by plugging in the values of the variables, we have;
K.E. = 0.0176 J = 1/2 × 0.006 kg × v²
v² = 0.0176 J/(1/2 × 0.006 kg) = 88/15 m²/s²
v = √(88/15 m²/s²) ≈ (2·√330)/15 m/s ≈ 2.42212 m/s
The speed of the pinball the instant it leaves the spring, v ≈ 2.42212 m/s
4. The height of the pinball is given by the following kinematic equation of motion;
[tex]v_h[/tex]² = u² - 2·g·h
Where;
[tex]v_h[/tex] = The velocity of the pinball at the given height = 1.3 m/s
u = v ≈ 2.42212 m/s (The initial velocity of the pinball as it the spring)
g = The acceleration due to gravity ≈ 9.8 m/s²
h = The height of the pinball above the ground
We get;
[tex]v_h[/tex]² = 1.3² = 2.42212² - 2 × 9.8 × h
∴ h = (2.42212² - 1.3²)/(2 × 9.8) ≈ 0.213
The height of the part where the pinball is located on the machine above the ground, h ≈ 0.213 m
A canoe moving down the river with a kinetic energy of 5J and a speed of 0.5m/s. What’s the mass of the canoe
A car travels at 12 m/s. The car then accelerates at 3 m/s2 until it reaches a speed of 18m/s.
Use the formula: (final velocity)2 – (initial velocity)2 = 2 x acceleration * distance
Calculate the distance the car travels.
A
2 m
B
6 m
С
30 m
D
60 m
Answer:
С. 30 m
Explanation:
Given the following data;
Initial velocity, U = 12m/s
Final velocity, V = 18m/s
Acceleration, a = 3m/s²
To find the distance, we would use the third equation of motion;
V ² = U² + 2aS
Substituting into the equation, we have
18² = 12² + 2*3*S
324 = 144 + 6S
6S = 324 - 144
6S = 180
S = 180/6
Distance, S = 30 meters.
