Answer:
1.04 s
Explanation:
The computation is shown below:
As we know that
t = t' × 1 ÷ (√(1 - (v/c)^2)
here
v = 0.5c
t = 1.20 -s
So,
1.20 = t' × 1 ÷ (√(1 - (0.5/c)^2)
1.20 = t' × 1 ÷ (√(1 - (0.5)^2)
1.20 = t' ÷ √0.75
1.20 = t' ÷ 0.866
t' = 0.866 × 1.20
= 1.04 s
The above formula should be applied
E=F*d/2 = k*d * d/2 =>
d^2= 2*E/k
d= sqrt(2*E/k)=sqrt(2*1J/1000N/m)=sqrt(20m^2)/100=0.045 m = 45 mm
Answer:
The height is : 60.025 m
Explanation:
The flowerpot falls off the balcony with zero launch angle
Given the time of fright as 3.5 s then ;
The formula to apply is ;
3.5²= 2H/9.8
12.25 =2H/9.8
12.25 * 9.8 = 2H
120.05 = 2H
120.05/2 = H
60.025 =H
The answer is D because theres nothing stopping that person from falling
The planet of an item will remain constant across the planet, but if you give it more mass, the gravitational force increases while the acceleration due to gravity remains constant.
<h3 /><h3>What is the difference between mass and weight?</h3>
The mass of the body is defined as the amount of matter a body has. It is denoted by m and its unit is kg. Mass is the quantity on which a lot of physical quantity depends.
Weight is defined as the amount of force an object exerts on the surface. It is given as the product of mass and the gravitational pull.
Mass is an independent quantity it never depends on the other. While weight is a dependent quantity that depends upon the gravitational pull.
The value of gravitational pull is different in the different parts of the universe. For example, on the earth, the value of gravitational acceleration is 9.81 m/sec².While on the moon it is g/6.
Weight is change according to the place or surrounding while the mass of the body is constant everywhere.
The planet of an item will remain constant across the cosmos, but if you give it more mass, the gravitational force increases while the acceleration of gravity remains constant.
If a planet's gravity weakens, the weight of that planet will likewise be altered. With an increase in mass, weight also rises.
Hence, the gravitational force increases while the acceleration due to gravity remains constant for the given case.
