Answer: The buoyant force is a result of pressure exerted by the fluid. The fluid pushes on all sides of an immersed object, but as pressure increases with depth, the push is stronger on the bottom surface of the object than in the top (as seen in ).

what is one effective way to calibrate a thermometer
Calibration can be defined as the way an instrument is adjusted such that the measurement the instrument gives after calibration is precise and accurate.
One effective way to calibrate a thermometer is the use of ice water.
A thermometer can be defined as the instrument used to measure the temperature of a person or a substance.
A thermometer should be calibrated regularly in order to maintain a high level of precision and accuracy.
One of the effective ways to calibrate a thermometer is through the use of ice water.
The steps to calibrate a thermometer are given below:
Get a bowl, place some ice cubes in it and add additional cold water to it. Place thermometer probe between 2 -3 inches deep in the water. For accurate calibration, make sure you prevent the thermometer from touching the sides of the glass. Stir and wait for a few seconds. The thermometer should be properly calibrated when you read the measurements and it says 32°FTo learn more, visit the link below:

Answer
both earthquakes and tsunamis have waves
Explanation:
Tsunamis are caused by earthquakes, underwater land slides, volcanic eruptions, and land sloping into the ocean. An earthquake is rapid shaking of the earths surface. It's no wonder earthquakes cause mass destruction, because they occur when two plates collide. Also earthquakes occur more often than tsunamis do.

Hii I need help ASAP with this physics question
A roller coaster has two vertical loops one after the other. The roller coaster has a speed of 7m/s at the top of the first loop with a height of 22.2m. It then proceeds around the second vertical loop with a height of 15.0m. What is the speed of the roller coaster at the top of the second vertical loop?
a.7m/s b.13.8m/s c.8.40m/s d.9.24m/s e.11.2m/s
Plz explain I can’t understand the question what I’m I supposed to use to calculate
Between the top of the first and the top of the second loop, the coaster has lost potential energy = mgh, where h = 22.2 - 15 = 7.2m
This energy would have converted to Kinetic. Write out an equation and the masses will cancel out. Does that hint help you to find the solution? If not, I will give you another hint.
a body dropped from a height reaches a velocity of 13m/s just before touching the ground. What is the initial height of the ball and the time of height
Hi there!
We can use the following (derived) equation to solve for the final velocity given height:
vf = √2gh
We can rearrange to solve for height:
vf² = 2gh
vf²/2g = h
Plug in the given values (g = 9.81 m/s²)
(13)²/2(9.81) = 8.614 m
We can calculate time using the equation:
vf = vi + at, where:
vi = initial velocity (since dropped from rest, = 0 m/s)
a = acceleration (in this instance, due to gravity)
Plug in values:
13 = at
13/a = t
13/9.81 = 1.325 sec

Pleaseee helppp I need help I don’t know how to do this
Answer:
1)So, the mass(m) of the tv is 75kg and the scale(weight)=825 N therefore you devide the weight by the mass which is equal to 11m/s^2
2)First things first you need to know the gravitational force here on earth which is 9.8(approximately 10) I will sove for 9.8 and 10 so you can choose
the fish has a mass of 2.4kg and the gravity= 9.8 so the weight is equal to the mass*gravity= 23.52
now if you use 10 as the gravity= 2.4*10= 24
3) here the weight is 250N and gravity is 9.8(10) so we just devide the weight by the gravity= 250/9.8= 25.51
250/10= 25( if gravity is 10)
Answer:
Explanation:
12.since W=mg where m is mass and g which is accelaration due to gravity,
g=825N/75kg
g=11 m/s^2
13.W= 2.4kg * 9.81m/s^2
=23.544kg m/s^2=23.544N
14.m=250N/9.81ms^-2
=25.48kg
Which of the following best describes why longitudinal waves cannot travel in space?
Answer:
A longitudinal wave travels by displacement of material objects.
Air (for instance) particles transmit waves by their oscillation
Space has no material particles to transmit these waves.
. In a wave, …………………… is carried from one place to another.
1.Energy
2.Transverse 3.Longitudinal
4.Medium
Answer:
The answer is energy it can be carried from one place to another.
please mark this as brainliest
Answer:
energy
Explanation:
In a wave phenomenon, energy can move from one location to another, yet the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position.

an elevator suspended by a vertical cable is moving downward but slowing down. the tension in the cable must be:
Answer:
F = M a is the vector equation involved
F = T - M g are the forces acting on the elevator (scalar equation)
T - M g = M a
T = M (a + g) remember this a scalar
If a is slowing down then it must have a positive acceleration upwards
Therefor the tension in the cable must be greater than zero
When the tension increases to M g, a has increased to zero
For a to be zero, no acceleration, T = M g

write the energy conversion when a moving car braking to stop completely
Answer:
Friction braking is the most commonly used braking method in modern vehicles. It involves the conversion of kinetic energy to thermal energy by applying friction to the moving parts of a system. The friction force resists motion and in turn generates heat, eventually bringing the velocity to zero.
