Two objects of mass 5 kg and 8 kg at rest F1 and F2 meters force applied on both the boxes respectively If the speed of both the objects after 5 sec become 16m/s and 15m/s respectively find the value of F1 and F2?
Answer:
F1 = 16 N and F2 = 24 N
Explanation:
Formula used => F = m×a and v-u= at
So, as we know force = mass × acc.
so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now
Here u= 0 as the objects are placed at rest initially..
thus, v= at
FOR 1ST BLOCK
16= <math> F1/5 </math> × 5 ==> F1 = 16 N
FOR 2ND BLOCK
15= <math> F2/ 8 </math> × 5 ==> F2= 24 N

A long platform is holding your physics teacher in the air above some hungry alligators. Your physics teacher has a mass of 75 kg and is located 2 m from one end. The 10.0 m platform has a mass of 10.0 kg, and its center of gravity is located 4.0 m from the same end. The platform is being held up by two students, one at either end.
a. What force is required by each student to hold the platform up?
Answer:
See Below.
Explanation:
I can't transpose the diagram onto Brainly. I'll do my best to describe what is going on.
Draw a horizontal line one inch from the each border of the page.To show what each of A and B are supporting, use an up arrow. Label the Ends A and B. B is on the right side.Put the physics teacher about 1.5 inches from B. His force goes down. Label it as 75 * 9.8 NewtonsPut the platform mass about 2.5 inches from BLabel it as 10 * 9.8 NewtonsB is the balance pointNow put in the distances. The lines are horizontalStudent A: 10 metersCenter of mass: 4 meters to BMass of Physics: 2 meters.Now you are ready to develop the equation
Clockwise
There is only 1 force where B is the Balance point that is going clockwise
10 * Force A
The AntiClockwise Moments
Platform: 4*10kg * 9.8 = 392 N m
Physics T: 2 * 75 * 9.8 = 1470 N m
So the Anti Clockwise moments = the clockwise moments.
10 * Force A = 392 NM + 1470NM Divide by 10. Remember that is in meters
Force A = 1862 N M / 10 10 M = 186 N
Does that make some sort of sense? It should Student A is the furthest distance from where all the action is at B. Therefore he is carrying the lightest weight.
Now what is the total force?
(75 + 10 ) * 9.8 = 85 * 9.8 = 833
This is one of those strange things that won't make sense until it does. Read the next sentence carefully. B is carrying most of the weight. Remember Newtons measure weight.
Support of A = 186 N
Support of B = x
Total of A+B = 933
186 + x = 833
x = 933 - 186
x = 647
So the forces are
A supports 186
B supports 647
You are standing on the bleachers in the gym. What supporting force are you experiencing?
a. Friction
b. Tension
c. Gravity
d. Normal
If a 2 kg ball is moving at 6 m/s to the right and then hits a wall and bounces back at - 4 m/s (left), what is the change in momentum (in kg*m/s)?
Answer:
The change in momentum (in kg*m/s) [tex]= 20[/tex]
Explanation:
The change in momentum is equal to
Final Momentum - Initial Momentum
As we know
Momentum is equal to the product of mass and velocity
M = m * v
Thus, change in momentum
[tex]m_2v_2 - m_1v_1[/tex]
here m1 = m2 = 2 Kg
Substituting the given values in above equation we get -
[tex]2 * 6 -( 2 *-4)\\12 + 8 = 20[/tex]kg m/s

Write two complete sentences for each question for a total of four complete sentences. What is the purpose of cellular respiration? How is cellular respiration similar to photosynthesis?
PLEASE HELP ME
Explanation:
The purpose of cellular respiration is the to provide energy for the body of an organism. In this process, food materials are broken down by complex metabolic actions usually with the availability of oxygen. Then, energy is liberated for use by an organism and the waste is expelled.
Cellular respiration and photosynthesis are both similar. In that they are ways by which organisms obtain nutrition. The food for plant is derived by the process of photosynthesis. Also, other organisms use this food for their own nourishment.

the bottom-right corner shows the wave emitted by the transmitter. Move the electron up and down, and
observe the wave it emits in the window. Change the speed of the motion of the electron. What
relationship do you notice between speed and wavelength?
Answer:
The wavelength decreases as the electron speeds up. The wavelength increases as the electron slows down.
Explanation:
A rocket is fired at 60 to the horizontal with an initial speed of 200m5 calculate it time of flight and it range on the horizontal plane
Answer:
See answer below
Explanation:
In order to do this, we just need to apply the expression to determine the time of flight. This is given by:
t = 2 V₀ Sinθ / g (1)
We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:
t = 2 * 200 Sin60° / 9.8
t = 35.348 sNow that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:
X = V * t (2)
We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:
X = 200 cos60° * 35.348
X = 100 * 35.348
X = 3534.8 mHope this helps
How is conduction shown here:
Conduction Transfers Thermal Energy Through Direct Contact
Answer:
Conduction is the transfer of heat between substances that are in direct contact with each other. ... Conduction occurs when a substance is heated, particles will gain more energy, and vibrate more. These molecules then bump into nearby particles and transfer some of their energy to them.

All materials are made up of elements. Which of the following best describes elements? A. Mixtures combine in several different ways to make many kinds of elements. B. Elements are unable to combine in order to make different compounds. Elements combine in several different ways to make many kinds of compounds. > D. Compounds combine in several different ways to make a limited number of elements,
Answer:
a.
Explanation:
Answer:
I am pretty sure it is C!
Explanation:
According to www.open.edu,
Elements are substances that are made from one type of atom.
Compounds are substances made from atoms of different elements joined by chemical bonds.
A mixture is made by simply mixing together elements and compounds.
Atoms are the basic building blocks.
i think A is incorrect because, while the statement may be correct, it is talking about Mixtures, not elements themselves!
B is incorrect because elements ARE able to combine to form compounds!
D is incorrect because ELEMENTS combine to create compounds, i am pretty sure compounds don't combine to create elements.
