If two runners take the same amount of time to run a mile, they have the same __________.A.
acceleration
B.
force
C.
mass
D.
velocity

Answers

Answer 1

Answer:
They have the same average speed over a mile.

If both of their miles are in straight lines, and in the same directions, and they
both take the same time, then their average velocities are also the same.

Answer 2

Answer:

its d. velocity i just took the test on edge

A stone is dropped from a height of 7.70 m how fast is it going when it is 5.25 m above the ground

Answers

The velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.

Velocity of the stone

The velocity of the stone at the given displacement is calculated as follows;

K.E = ΔP.E

¹/₂mv² = mgh

v = √2gΔh

v = √[2(9.8)(7.7 - 5.25)]

v = 6.93 m/s

Thus, the velocity of the stone when it is 5.25 m above the ground is determined as 6.93 m/s.

your friend wants to know the amount of salt added to her favorite fast food French fries. what would you recommend that she do to find out the amount of salt ?

Answers

Every fast-food chain is required by law to make the nutrition content of the
items on its menu publicly available.

My friend should walk into her favorite place, or into the nearest McRonald's,
Bendy's, Tennessee Fried Turkey, Bulgur King, Plucky Please, White Palace,
Pita Hut, Carl's Senior, Back in the Box, or any of those others, ask to see
the Manager, and ask the manager for a chart of nutritional information that
includes their french fries.

To be nice about it, she should do this at a time when the place is not too busy,
and the manager doesn't have a lot of more-important things that need to be
doneright now.

Under the french fries, look at the serving size, and the figure for "Sodium"
in that serving, which is the nutrient that your body gets from salt. Less is
better. More is worse. For an adult, the CDC Institute of Medicine says
that 1500mg a day is 'adequate' for an adult. The US Food and Drug
Administration recommends that adults should get 'no more than' 2300mg
in a day. People who have high blood pressure are supposed to watch it,
and take in a lot less sodium.

And there are organizations with official-sounding names that totally dispute
all of this.

But to answer your question, that's what she should do to learn the amount
of salt used at the place where likes to get her french fries.

What is the resistance of an ideal ammeter voltmeter ?

Answers

All the current being measured has to flow through the ammeter. So in order to avoid
any change in the circuit caused by the ammeter, its resistance should ideally be zero.

The voltmeter measures the voltage between two points. It must be connected
between those points, and in parallel with everything between them in the circuit.
In order to avoid any change in the circuit caused by the voltmeter, its resistance
should ideally be infinite.

Final answer:

An ideal ammeter has zero resistance to avoid altering the current it measures, while an ideal voltmeter has infinite resistance to prevent drawing current from the device it's measuring the voltage of.

Explanation:

The resistance of an ideal ammeter is zero ohms. This ensures that it doesn't interfere with the current it is measuring. An ammeter is connected in series with the circuit, and if the resistance were greater than zero, it would decrease the amount of current circulating in the circuit.

On the other hand, an ideal voltmeter has infinite resistance. This happens because a voltmeter is connected in parallel with a device to measure its voltage, and to avoid drawing current from the device, an ideal voltmeter should have infinite resistance.
