why does an object appear to be moving faster as it moves away from the axis of rotation
Answer:
I suppose that this is a problem of rotation with constant angular velocity.
This can be answered with arcs.
Suppose that we have a circle of radius R, and an angle A (A expressed in radians)
The length of that arc will be:
L = R*A
Now, a rotating object that rotates at a constant angular velocity, in a time t moves an angle A.
so if this object is moving in a circle of radius R, in the time t the distance traveled is the same that we found above.
L = R*A
Now, if the object moves away from the axis of rotation, we have that the radius of the circle R increases, then also does the value of L (the distance traveled in the time t)
Then, when the object moves away from the axis of rotation, in the same time t, the distance traveled will be higher, which means tath the tangential velocty increased (regardless the fact that the angular velocity is constant)

A stone is thrown with an initial upward velocity of 7.0 m/s and experiences negligible air resistance. If we take upward as the positive direction, what is the velocity of the stone after 0.50 s?
Answer:
2.1 m/s
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 7 m/s
Time (t) = 0.50 s
Final velocity (v) =?
Since the is thrown upward, it means that the stone is going against gravity. Thus, the value of the acceleration due to gravity will be negative i.e – 9.8 m/s²
Thus, we can obtain the velocity of the stone after 0.50 s as follow:
Initial velocity (u) = 7 m/s
Time (t) = 0.50 s
Acceleration due to gravity (g) = – 9.8 m/s²
Final velocity (v) =?
v = u + gt
v = 7 + (– 9.8 × 0.5)
v = 7 – 4.9
v = 2.1 m/s
Therefore the velocity of the stone after 0.5 s is 2.1 m/s.

What is the product of frequency and time period????
Answer:
k Nishant
Explanation:
the product of the time period of the sound wave and its frequency is equal to unityTurner’s treadmill starts with a velocity of −3.0 m/s and speeds up at regular intervals during a half-hour workout.After 33 min, the treadmill has a velocity of −6.7 m/s. What is the average acceleration of the treadmill during this period? Answer in units of m/s^2
Explanation:
Acceleration is change in velocity over change in time.
a = Δv / Δt
a = (-6.8 m/s − (-3.0 m/s)) / (33 min × 60 s/min)
a = (-3.8 m/s) / (1980 s)
a = -0.0019 m/s²

If the pressure of a gas is increased, then the volume will decrease because the particles of the gas will be forced more closely together.
The independent variable is
.
The dependent variable is
.
Then the independent variable is the pressure of the gas while the dependent variable is the volume of the gas as it depends on the variation in the pressure of the gas.
What is an ideal gas?It is an imaginary gas for which the volume occupies by it is negligible, this gas does not exist in a practical situation and the concept of an ideal gas is only the theoretical one,
A gas's volume will decrease as its pressure rises because the gas's particles will be pressed closer together.
As the volume of the gas depends on the fluctuation in the gas's pressure, the independent variable in this situation is the gas's pressure.

If two conductors are not touching but are close to each other, a large enough voltage will cause an _________________ to occur between the conductors.
Answer:
Electrical breakdown.
Explanation:
When two conductors are relatively close enough, and have a very large voltage between them, it can lead to a Dielectric breakdown. A dielectric breakdown occurs when an insulator is subjected to a high enough voltage, suddenly becomes an electrical conductor and electric current flows through it. The air between the conductors is the insulator that breaks down, leading to an electrical discharge arc to flow between the two conductors. This electrical breakdown can cause catastrophic failure of electrical equipment, and fire hazards.

While participating in a blood drive at school, Keona learns that blood has a density of 1.06 g/mL. She donates one pint of blood, which is equal to 473.176 mL. What is the mass of the blood Keona donates, to the nearest hundredth of a gram?
Answer:
m≈501.57 g
Explanation:
The density formula is:
d=m/v
Let’s rearrange the formula for m. m is being divided by v. The inverse of division is multiplication, so multiply both aides by v.
d*v= m/v*v
d*v=m
The mass can be found by multiply the density and the volume.
m=d*v
The density is 1.06 grams per milliliter and the volume is 473.176 milliliters.
d= 1.06 g/mL
v= 473.176 mL
Substitute the values into the formula.
m= 1.06 g/mL * 473.176 mL
Multiply. When multiplying, the mL will cancel out.
m= 501.56656 g
Let’s round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7 in the hundredth place.
m ≈501.57 g
The mass is about 501.57 grams.
Answer:
501.57 g

When the course deviation indicator (CDI) needle is centered during an omnireceiver check using a VOR test signal (VOT), the omnibearing selector (OBS) and the TO/FROM indicator should read:_______
Answer:
0° FROM or 180° TO
Explanation:
A course deviation indicator or the CDI may be defined as an avionics tool or instrument that is used in the aircraft navigation which is used to determine an aircraft's lateral position with relation to a course.
While using the VOT service, we should tune the VOT frequency of the VOR receiver. And with the CDI leveled centered, the omnibearing selector or the OBS should read as 0° with the TO/FROM indicator showing 'FROM'. Else the OBS should read as 180° with the TO/FROM indication showing 'TO.'
How can an object's motion be predicted by using a graph?

Use the formula to solve for the variable of d
v=d/t
A. d = v/t
B. d = vd
C. d = vt
D. d = t/v
a is correct
Explanation:
beacuse d is directly proportional bto velocity and the time taken
Answer:
C. d=vt
Explanation:
We are given this formula:
[tex]v=\frac{d}{t}[/tex]
and asked to solve for the variable d.
In order to solve for d, we must isolate it on one side of the equation.
d is being divided by t. The inverse of division is multiplication. Multiply both sides of the equation by t.
[tex]t*v=\frac{d}{t} *t[/tex]
[tex]t*v=d[/tex]
[tex]tv=d[/tex]
[tex]d=tv[/tex]
Due to the commutative property of multiplication, we can switch the v and the t.
[tex]d=vt[/tex]
The formula solved for d is d=vt and C is the correct answer.
