In my opinion, mental health can affect all of these options. However, I think the answer this is looking for would be "A person's ability to breathe"
Mental health definitely affects motivation; and motivation affects mental health. Motivation is a driving force behind human behaviours; its absence can lead to mental illnesses such as depression. Often when someone is depressed, they lack the motivation to do things.
Mental health can affect decision making as well- for example, if someone has anxiety, decision-making can be harder. Anxiety disrupts the decision-making regions in the prefrontal cortex.
Mental health can also affect memory- Depression has been linked to memory problems, such as forgetfulness. Depression is associated with short-term memory loss. Stress and anxiety can also lead to poor memory.
I would say that panic attacks can inhibit a person from breathing, but considering the options I would say that's the best one. Breathing is more of a physical thing, not associated with the brain or mental condition. So the answer is A person's ability to breathe.

A 200kg bumper car moving 3 m/s collides head on with a 392kg bumper car moving 6m/s. After impact, the larger car continues traveling in the same direction with a velocity of 1.6 m/s . Determine the speed of the other car.
Answer:
the final speed of the smaller car is 5.624 m/s
Explanation:
Given;
mass of the small car, m₁ = 200 kg
initial velocity of the small car, u₁ = 3 m/s
mass of the larger car, m₂ = 392 kg
initial velocity of the larger car, u₂ = 6 m/s
final velocity of the larger car, v₂ = 1.6 m/s
let the direction of the larger car be positive
let the direction of the smaller car be negative
Apply the principle of conservation of linear momentum to determine the final speed of the smaller car.
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
200(-3) + 392(6) = 200v₁ + 392 x 1.6
-600 + 2352 = 200v₁ + 627.2
1752 = 200v₁ + 627.2
1752 - 627.2 = 200v₁
1124.8 = 200v₁
v₁ = 1124.8/200
v₁ = 5.624 m/s
Therefore, the final speed of the smaller car is 5.624 m/s

Answer:
F = 4117.64
Explanation:
First, we will calculate the acceleration of the hand, by using the third equation of motion:
[tex]2as = v_f^2 - v_i^2\\[/tex]
where,
a = acceleration = ?
s = distance covered = compression = 8.5 cm = 0.085 m
vf = final speed = 0 m/s
vi = iniial speed = 10 m/s
Therefore,
[tex]2a(0.085\ m) = (0\ m/s)^2-(10\ m/s)^2\\a = - 588.23\ m/s^2[/tex]
negative sign hows deceleration.
Now, we will calculate the force exerted by the hand:
[tex]F = ma = (7\ kg)(588.23\ m/s^2)\\[/tex]
F = 4117.64 N
a) How is the single covalent bond usually shown in each diagram?
In a car collision, is it better for the passenger if the change in momentum is over a short period of time or a long period of time?
Explanation:
The force on the passenger will be F = ma
Here, m does not change, but a is the variable.
If the cars slows down very fast, the acceleration will be higher, and thus the force will be higher.
If the acceleration is lower, the force will be lower as well, which would be the most desirable scenario for the passenger.

A uniform electric field, with a magnitude of 449 N/C, is directed parallel to the positive x-axis. If the potential at x= 4.59 m is 966 V, what is the potential at x= 1.61 m?
Answer:
2.334 kV
Explanation:
Since the electric field strength Ecosθ = -ΔV/Δx = -(V₂ - V₁)/(x₂ - x₁)
where V₁ = potential at x₁ = 966 V, x₁ = 4.59 m, V₂ = potential at x₂ = unknown, x₂ = 1.61 m and θ = angle between E and the x - axis.
Given that E = + 449 N/C and since it is directed parallel to the positive x - axis, θ = 0°
So,
Ecosθ = -ΔV/Δx
Ecos0° = -ΔV/Δx
E = -ΔV/Δx
E = -(V₂ - V₁)/(x₂ - x₁)
making V₂ subject of the formula, we have
-E(x₂ - x₁) = V₂ - V₁
-E(x₂ - x₁) + V₁ = V₂
V₂ = V₁ - E(x₂ - x₁)
Substituting the values of the variables into the equation, we have
V₂ = V₁ - E(x₂ - x₁)
V₂ = 966 V - 449 N/C(1.61 m - 4.59 m)
V₂ = 966 V - 449 N/C(-2.98 m)
V₂ = 966 V + 1,338.02 Nm/C
V₂ = 966 V + 1,338.02 V
V₂ = 2,334.02 V
V₂ ≅ 2,334 V
V₂ = 2.334 kV
Utility companies charge by the kilowatt-hour. The number of kilowatt-hours used equals the number of kilowatts multiplied by the number of hours an electrical device was used. How long would it take for a 50-watt fan to use 1 kilowatt-hour of electricity? (Hint: 50 watts = 0.05 kilowatts.)
Answer:
t = 3 minutes
Explanation:
Given that,
Power of fan, P = 50 W
Energy used, E = 1 kWh
We know that,
Energy = Power/time
As, 50 watts = 0.05 kilowatts
So,
[tex]t=\dfrac{P}{E}\\\\t=\dfrac{0.05\ kW}{1\ kWh}\\\\t=0.05\ h[/tex]
or
t = 3 min
So, the required time is equal to 3 minutes.

A block is at the bottom of a frictionless ramp and is given a kick so that it has some initial velocity and starts to slide up the ramp. There
is no air resistance. Which of the following is true of the energy of the block as it slides?
(A) Its potential energy will increase; its kinetic energy will decrease.
(C) Both its potential and kinetic energies will increase.
(B) Its potential energy will decrease; its kinetic energy will increase.
(D) Both its potential and kinetic energies will decrease.
Answer:
Explanation:
The answer is A. First of all, due to the First Law of Thermodynamics, energy cannot be created or destroyed, it only changes form. That being said, it is impossible for the PE and the KE to both increase or decrease at the same time. The second one starts decreasing, the other starts increasing at the exact same rate. PE exists or is at its highest when an object has the potential to fall to a point lower than it is, and it is at this point where Kinetic energy is the lowest. If this block is kicked UP a ramp, which is odd but there you have it, the potential energy increases as it gets higher off the ground. Because of gravity, and assuming that once the block is kicked, the foot that kicked it is no longer important to it (meaning it's not being pushed up, it's just kicked once and that's it) and it will slow down very quickly. KE exists where there is a great amount of velocity.
The answer is A.

heena wants to measure the volume of a ball that is 24 cm across. How should she set up her equation? v = one-third pi 24 squared (12). v = one-third p 12 squared (24). v = four-thirds pi 24 cubed. v = four-thirds pi 12 cubed.
Answer:
v = four-thirds pi 12 cubed.
Explanation:
A ball has a spherical shape. The volume of a spherical shape can be calculated using the following formula:
[tex]V = \frac{4}{3} \pi r^3[/tex]
where,
V = Volume of Ball = ?
d = diameter of the ball = length across the ball = 24 cm
r = radius of ball = d/2 = 24 cm/2 = 12 cm
Therefore,
[tex]V = \frac{4}{3}\pi (12)^3[/tex]
Hence, the correct answer is:
v = four-thirds pi 12 cubed.

Explanation:
The law of conservation of energy is a physical law that states energy cannot be created or destroyed but may be changed from one form to another. Another way of stating this law of chemistry is to say the total energy of an isolated system remains constant or is conserved within a given frame of reference.
A laser pulse of duration 25 ms has a total energy of 1.4 J. The wavelength of this radiation is
567 nm. How many photons are emitted in one pulse? Let 1 eV = 1.60 x 10-19 J, the mass of
an electron m=9.11 10-31
kg, the speed of light c= 3.00 x 108 m/s, and Planck's constant h
= 4.136 10-15 eV .s.
Answer:
n = 4 x 10¹⁸ photons
Explanation:
First, we will calculate the energy of one photon in the radiation:
[tex]E = \frac{hc}{\lambda}\\\\[/tex]
where,
E = Energy of one photon = ?
h = Plank's Constant = 6.625 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of radiation = 567 nm = 5.67 x 10⁻⁷ m
Therefore,
[tex]E = \frac{(6.625\ x\ 10^{-34}\ J.s)(3\ x\ 10^8\ m/s)}{5.67\ x\ 10^{-7}\ m}[/tex]
E = 3.505 x 10⁻¹⁹ J
Now, the number of photons to make up the total energy can be calculated as follows:
[tex]Total\ Energy = nE\\1.4\ J = n(3.505\ x\ 10^{-19}\ J)\\n = \frac{1.4\ J}{3.505\ x\ 10^{-19}\ J}\\[/tex]

3.Three resistors of 25.0Ω, 30.0Ω, and 40.0Ω are in a series circuit with a 6.0-volt battery. What is the current in the circuit?
please answer by steps
Answer:
Current = 0.063 Amperes
Explanation:
Let the three resistors be R1, R2, and R3 respectively.
Given the following data;
R1 = 25.0Ω,
R2 = 30.0Ω
R3 = 40.0Ω
Voltage = 6 Volts
First of all, we would determine the equivalent or total resistance;
Total resistance (in series) = R1 + R2 + R3
Total resistance = 25.0Ω + 30.0Ω + 40.0Ω
Total resistance = 95 Ω
Next, we find the current flowing through the circuit;
Voltage = current * resistance
Substituting into the formula, we have;
6 = current * 95
Current = 6/95
Current = 0.063 Amperes
