Which of the following are possible non-SI units to describe the rate of
acceleration? (Choose all that apply)
1) meters per second per minute
2) miles per kilometer per
second
3) miles per hour per second
4) kilometers per hour squared
5) meters per hour per kilometer
6) kilometers per minute
The possible non-SI units to describe the rate of acceleration is the kilometers per hour squared. That is option 4.
What is acceleration?Acceleration is the relationship that exists between velocity and time. It is defined as the change of velocity in both speed and direction with respect to time.
The formula for acceleration is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.
Velocity is defined as the rate of objects position with time.
The SI units of velocity = meter/seconds
Substitute for velocity in first equation:
a = meter/sec/sec
a = meter/sec²
But 1000meters = 1 Km
3600 secs = 1 hour
Therefore, the possible non-SI units to describe the rate of acceleration is the kilometers per hour squared.

Answer:
initial velocity (u) = 0 m/s
Final velocity (v) =124 m/s
Time (t) = 3.7 s
acceleration (a) =?
Now
A =V-U /T
= 124-0 /3.7

A dog pulls on a leash with a force of 15 23 is a big dog. The leash makes an angle of 36.7 degrees to the horizontal. What are the x
and y components of the force?
Answer:
[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]
Explanation:
The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N
[tex]Force = 15N[/tex]
[tex]\theta = 36.7[/tex] to the horizontal
Required
Solve for the x and y components
Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.
[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component
[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component
Calculating the y component.
Substitute 15 for Force and 36.7 for [tex]\theta[/tex]
[tex]Sin\theta = \frac{y}{Force}[/tex] becomes
[tex]Sin(36.7) = \frac{y}{15}[/tex]
Make y the subject
[tex]y = 15 * Sin(36.7)[/tex]
[tex]y = 15 * 0.5976[/tex]
[tex]y = 8.964N[/tex]
Calculating the x component.
Substitute 15 for Force and 36.7 for [tex]\theta[/tex]
[tex]Cos\theta = \frac{x}{Force}[/tex] becomes
[tex]Cos(36.7) = \frac{x}{15}[/tex]
Make y the subject
[tex]x = 15 * Cos(36.7)[/tex]
[tex]x = 15 * 0.8018[/tex]
[tex]x = 12.027N[/tex]
Hence, the x and y components of the force are: 8.964N and 12.027N respectively.

A lava lamp is a decorative item found in some homes. The lamp portion contains a waxy substance in a liquid medium. When the lamp is plugged in, a bulb at the base of the lamp slowly heats the waxy substance sitting at the bottom of the liquid. Eventually, the waxy substance will separate into globs that quickly rise to the top of the lamp where the surrounding liquid cools them and causes them to fall back to the bottom. Based on the information provided, a lava lamp could be used to provide an example of which process of thermal energy transfer?
Answer:
Conduction, convection, and radiation
Explanation:
Conduction is the process in which energy is transferred from a hot body to a cooler body. Convection is a process by which heat is transferred as a result of the movement of heated fluid in the form of air or water. Radiation refers to the transmission of energy through a material medium.
Based on the information provided, a lava lamp could be used to provide an example of conduction, convection, and radiation.
A stone dropped from the top of a 80m high building strikes the ground at 40 m/s after falling for 4 seconds. The stone's potential energy with respect to the ground is equal to its kinetic energy
Answer:
A
Explanation:
Given that a stone dropped from the top of a 80m high building strikes the ground at 40 m/s after falling for 4 seconds. The stone's potential energy with respect to the ground is equal to its kinetic energy. (use 9 - 10 m/s)
O at the moment of impact
2 seconds after the stone is released after the stone has fallen 40 m
when the stone is moving at 20 m/s
At the top of the hill, the P.E = mgh
P.E = 10 × 80 × m
P.E = 800m
At the moment of impact, K.E = 1/2mv^2
K.E = 1/2 × 40^2 × m
K.E = 1/2 × 1600 × m
K.E = 800m
Since both P.E and K.E are the same, we can therefore conclude that the stone's potential energy with respect to the ground is equal to its kinetic energy at the moment of impact.

An electric energy distributor supplies each household 220
volts of voltage and 60 A of current. Applying your knowledge on Ohm's Law, in what way your appliances be used at home to maintain a safe amount of current?
Answer:
Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current
Explanation:
According to Ohm's law, V = IR
V is the potential difference = 220volts
I is the current = 60 A
R is the resistance (Load)
Calculating the load R
R = V/I
R = 220/60
R = 3.67 ohms
Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

Starting from rest, a spinning disk accelerates constantly to a final rotational speed, ω , in a period of time, Δ Δ t. What expression best represents the revolutions the disk has turned through? A) ω Δ Δ t /2 π B) Δ4 ω Δ t 4 π C)Δ22 ω Δ t 2 2 D) Δ ω Δ t E) 2Δ 2 π ω Δ t
Answer:
the correct one is B, θ = [tex]\frac{1}{4\pi }[/tex] w t [rev]
Explanation:
This is a rotational kinematics exercise
w = w₀ + α t
w² = w₀² + 2 α θ
indicate that part of rest whereby the initial angular velocity is zero
w = α t -> α = w/t
w² = 2 α θ
we substitute
w² = 2 (w / t) θ
w = 2 θ / t
θ = w t / 2
This angle is given in radians, let's reduce to revolutions = 2π rad = 1 rev
θ = w t / 2 rad (1 rev / 2π rad)
θ = [tex]\frac{1}{4\pi }[/tex] w t [rev]
when checking the answers, the correct one is B, even though he has some mistakes in his writing
Why is air warmer near Earth's surface?
A.
The Sun heats Earth's surface, and in turn the air above it is heated.
B.
Warm air is more dense and sits on top of Earth's surface.
C.
Warm air is less dense and sits on Earth's surface HELP PLZ!!
Answer:
I am pretty sure it is A!
:D
The air is warmer near Earth's surface because warm air is denser and sits on top of the Earth's surface. The correct option is B.
What is air density?The mass of the air per unit volume is known as the air density. Its unit is kg/m³.
Due to the lower pressures in the air above, air expands when it rises. cooling air expands.
The hottest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends.
Because warm air is denser and lies on top of the surface of the Earth, it is warmer near the surface of the earth.
Hence, the correct option is B.
