Answer:
The density of the metal is 5200 kg/m³.
Explanation:
Given that,
Weight in air= 0.10400 N
Weight in water = 0.08400 N
We need to calculate the density of metal
Let  be the density of metal and
 be the density of metal and  be the density of water is 1000kg/m³.
 be the density of water is 1000kg/m³.
V is volume of solid.
The weight of metal in air is



 .....(I)
.....(I)
The weight of metal in water is
Using buoyancy force


We know that,
 ....(I)
....(I)
Put the value of  in equation (I)
 in equation (I)

Put the value of Vg in equation (II)



Hence, The density of the metal is 5200 kg/m³.
 
        
             
        
        
        
The force is reasonable for making fusion possible in the Sun is heat energy.
<h3>What is nuclear fission and fusion?</h3>
When the slow moving neutrons are bombarded with the heavy radioactive nuclei, the product is the more number of neutrons are produced with the large amount of energy. This multiplying process is called nuclear fusion.
The amount of energy produced in such a reaction can be calculated using the equivalence of mass and energy relationship.
E = mc²
The same happens in nuclear fusion where large amount of energy is needed to make more heavy nuclei.
Thus, fusion requires heat energy to continue the reaction.

Explanation:
P = W/time
W = F*d
You have control over how fast you go up the stairs.
You also have control over how far up the stairs you go.
Therefore the answer is
If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.
 
        
             
        
        
        
Answer: O:right
Explanation: In this case you place your finger on the current, and your fingers should curl showing the way, you must use your right hand in this case, otherwise that would mean the fingers on your left would bend way back, and snap off, (Not really lol,  just saying)
 
        
             
        
        
        
Answer:
(a)   v = 5.42m/s
(b)   vo = 4.64m/s
(c)   a = 2874.28m/s^2
(d)   Δy = 5.11*10^-3m
Explanation:
(a) The velocity of the ball before it hits the floor is given by:
 (1)
        (1)
g: gravitational acceleration = 9.8m/s^2
h: height where the ball falls down = 1.50m

The speed of the ball is 5.42m/s
(b) To calculate the velocity of the ball, after it leaves the floor, you use the information of the maximum height reached by the ball after it leaves the floor.
You use the following formula:
 (2)
       (2)
vo: velocity of the ball where it starts its motion upward
You solve for vo and replace the values of the parameters:

The velocity of the ball is 4.64m/s
(c) The acceleration is given by:


The acceleration of the ball is 2874.28/s^2
(d) The compression of the ball is:

THe compression of the ball when it strikes the floor is 5.11*10^-3m
