a body has a weight of 2.8 Newtons what is the Mass of the body in grams
Answer:
285.7 g
Explanation:
Weight = mass x gravity
mass has units of kilograms
gravity is 9.8 m/s²
newton units are kg m / s²
So:
2.8 kg m/s² = mass x 9.8 m/s²
Divide both sides by 9.8
2.8 kg m/s²
---------------- = mass in kg = 0.2857kg
9.8 m/s²
Convert kilograms to grams by multiplying by 1000
0.2857kg 1000 g
-------------- X --------------- = 285.7g
1 1 kg

The tallest volcano on Mars
A
is three times the height of Mt. Everest.
B
is almost as tall as Mt. Everest.
C
has been visited 44 times.
D
is wet, rocky and cold.
Answer: Is three times the height of Mt. Everest
Explanation:
Using the process of elimination we can rule out “D” Because its a volcano, C because it says we have visited mars 44 times not the volcano, B because in the passage is literally says “3 times the size of Mt. Everest”.

Which statement explains whether or not a person should use an experiment of a ball rolling down a hill as evidence that the force of gravity pulls objects straight down?(1 point) They should use it. Any experiment on Earth involving natural motion will provide direct evidence that gravity pulls objects straight down. They should use it. Any experiment on Earth involving natural motion will provide direct evidence that gravity pulls objects straight down. They should not use it. The experiment has several dimensions of motion, including one parallel to the ground, so the motion of the ball does not directly test the force of gravity. They should not use it. The experiment has several dimensions of motion, including one parallel to the ground, so the motion of the ball does not directly test the force of gravity. They should use it. The experiment shows the ball falls toward the bottom of the hill, so it provides direct evidence that gravity pulls an object downward. They should use it. The experiment shows the ball falls toward the bottom of the hill, so it provides direct evidence that gravity pulls an object downward. They should not use it. Gravity should be tested in space, and this experiment could only be tested on Earth.
The ball raised up the hill is given gravitational potential energy, which
causes it to roll spontaneously down the hill.
The statement that explains whether the ball rolling down the hill
experiment should be used is; The experiment shows the ball falls toward
the bottom of the hill, so it provides direct evidence that gravity pulls an
object downward. They should use it.
Reason:
The equation for the velocity of a ball falling down a hill is [tex]v = \sqrt{\dfrac{10}{7} \cdot g \cdot h}[/tex]
Therefore, by increasing the height from which the ball rolls down the hill,
the velocity of the ball increases, which indicates that the ball is
accelerating, and therefore, being acted on by a force, the force of gravity.
Therefore;
Given that the ball falls or moves with increasing speed towards
the bottom of the hill, which shows that the motion is due to Earth's pull
known as the gravitational force, the experiment should be used.

what is the initial velocity of an object thrown straight up that takes 5 seconds to reach its highest point?
Answer:
50 [m/s].
Explanation:
1) formula is: V-V₀=g*t, where V₀ - final velocity (it is 0), V - required initial velocity, g≈10 [m/s²] and t - elapsed time.
2) according to the formula above:
V=g*t; ⇒ V=5*10=50 [m/s].
A cannon is fired with an initial horizontal velocity of 20 m/s and initial vertical velocity of 25 m/s. After 3s in the air, the canon hits it’s target. How far away(in meters) was the canon from its target? Answer:_____m
Answer:
60 m
Explanation:
After 3 seconds of travel at 20 m/s, the projectile is 3·20 = 60 meters horizontally from the cannon.
__
The vertical height after 3 seconds is 0.9 m, so the straight-line distance from cannon to target is √(60^2 +0.9^2) ≈ 60.007 meters.

If the activity of a source is 70 Bq after 2 years, and 35 Bq after 15 years. How long will be until the activity is 8.75 Bq?
Answer:
So if the half-life is two days, four half-lives is 8 days. Suppose a sample has a count rate of 3,200 Becquerel (Bq) at the start, then its count rate after 8 days would be 1/16th of 3,200 Bq = 200 Bq.

A 1,336 kg car drives around a flat 199-m-diameter circular track at 22 m/s. What is the
magnitude of the net force on the car?
Hi there!
This is an example of Uniform Circular Motion, thus:
Net Force = Centripetal force
∑F = mv²/r
Plug in the given values. Remember to convert from diameter to radius, first.
d = 199m
r = d/2 = 199/2 = 99.5 m
∑F = 1336(22²)/99.5 = 6498.73 N

like charges repelunlike charges attractswhat is the central idea for stacking rocks vertically to test the effects of forces
Answer:
You can see how forces can stack on one another by comparing the normal force of the bottom most rock to the normal force of the upper most rock.
Explanation:
Say you have 3 rocks all with mass m=3kg
These 3 rocks will all have the gravitational force of -29.4N (multiply 3kg by -9.8m/s^2)
If none of the rocks are stacked, then they all have the same normal force as well (29.4N)
However, stack them, and see how their normal forces change.
m1 will continue to have a normal force of 29.4N
m2 will now have a normal force of 58.8
m3 will now have a normal force of 88.2
Though they all retain the same gravitational force, their normal force changes depending on the forces acting down on them.
Mass 1 have no forces acting downwards other than gravity.
Mass 2 has the force of mass 1 and gravity acting down on it.
Mass 3 has the force of mass 1, mass 2, and gravity acting down on it.
A force unit is defined as the product of a mass unit and a unit of
acceleration.
time.
velocity.
displacement.
Answer:
A force unit is defined as the product of a mass unit and a unit of acceleration.
Answer:
Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.
Explanation:
Force = M (Mass) * A (Acceleration)
The SI unit of Mass = KG
S.I. unit of acceleration is m/sec/sec = m/sec2
Hence, Unit of force is Kg m/Sec2
Since force is used so often, S. I. gives this unit a special name:
1 Newton = 1 kg m/sec2
what is the physical property of a star used to classify the stars by spectral type?

2. Both stretching and constricting exercises are important for muscle health.
A.
True
B.
False
Answer:
B Both are directly related to movement.
Endocrine system and muscular system are directly related to movement while both stretching and constricting exercises are important for muscle health. So, the correct options for 1 and 2 are B and A respectively.
What is Endocrine system?The endocrine system is defined as the communication system made up of feedback loops that send hormones released by an organism's internal glands into the circulatory system, controlling distant target organs. The neurological control center for all endocrine systems in vertebrates is the hypothalamus. The endocrine glands lack ducts that would transport their output to the surface. These are known as glands without ducts.
Growth and development, metabolism, and reproduction are just a few of the essential processes in the body that are regulated by the hormones the endocrine system secretes. Movement has a close relationship with the endocrine and muscle systems.
Therefore, the correct options for 1 and 2 are B and A respectively.
