When an object is seen moving in relation to a stationary object, the stationary object is called the frame of reference or reference point. Please select the best answer from the choices provided T F

Answers

Answer 1

Answer:
From the choices provided, the better answer is ' T ', being the
one-letter acronym for the words "true", "truth", and "trust".

This choice is the preferred one, because the statement that
precedes it, dealing with relative motion, is a factually correct
statement.

What does Dependent viable meaning in science

Answers

Its the variable which you measure in an experiment. For example, you're conducting an experiment in order to find out how proportions of water affect plant growth, then, your dependent variable should be the height of the plants in the experiment.

What is the total energy of a 175,000kg shuttle orbiting the Earth at 600km above Earth's surface?

Answers

m = 175,000 kg
g = 10 m/s^2
h = 600,000 m

Ep = mgh
Ep = 1050 * 10^9 [J]

Lithium has 3 protons. how many neutrons are in the isotope lithium -8

Answers

Answer:

5 neutrons

Explanation:

Both protons and neutrons have a mass of about 1 atomic mass unit (amu). The number in the notation for an isotope is its mass in amu. That means the number is essentially the sum of protons and neutrons in the isotope (electrons don't contribute significantly to the mass).

If lithium has 3 protons, lithium-8 has 8 - 3 = 5 neutrons.

It should be 5 neutrons

C. The driver is looking at her phone and has a total reaction time of 4.6 seconds as the car is moving at a constant speed of 11 m/s. If the driver slams on her brakes and slows down at a rate of -8.2 m/s2, what is the stopping distance for the car in this situation

Answers

Answer:

The stopping distance for the car when the driver slams on her brakes is 7.38 m.

Explanation:

The distance traveled for the car after stopping can be found using the following equation:

$v_(f)^(2) = v_(0)^(2) + 2ad$

Where:

vf is the final speed = 0 (it stops)

v₀ is the initial speed = 11 m/s

a is the acceleration = -8.2 m/s²

d is the distance =?

When the driver slams on her brakes the distance traveled is:

$d = -(v_(0)^(2))/(2a) = -((11 m/s)^(2))/(2*(-8.2 m/s^(2))) = 7.38 m$

Therefore, the stopping distance for the car when the driver slams on her brakes is 7.38 m.

I hope it helps you!

what is the displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south

Answers

The displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south will be 1 mile in the east direction.

What is the displacement?

A displacement is a vector in engineering and mechanics that has a length equal to the shortest route between a point P's initial and final positions.

The displacement is the vector quantity that depends on the magnitude as well as direction. And follows the law of vector addition.

The cyclist who travels 1 mile north 1 mile east then finally 1 mile south. Then the diagram is drawn below.

From the graph, the displacement is given as,

Displacement = 1 - 0

Displacement = 1 mile

The displacement of a cyclist who travels 1 mile north 1 mile east then finally 1 mile south will be 1 mile in the east direction.

An article in a magazine denies that Earth is warming and climate change is occurring. The writer reports that this season was the snowiest winter on record for the Northeast, with lower than average temperatures for the region. Because of the low temperatures, the writer concludes that climate change cannot possibly be occurring. What question should you ask the writer to clarify whether his stance on climate change is scientifically sound?(A) Did the snowstorms cause extensive damage?(B) Was this the coldest month on record for this region?(C) Were the snowfall totals of each storm larger or smaller than last year?(D) Were long-term temperature changes investigated in addition to short-term change?
