Any of the pieces of hard whitish tissue making up the skeleton in humans and other vertebrates.
The calcified material of which bones consist
As we know that the formula of kinetic energy will be
![KE = \frac{1}{2} mv^2](https://tex.z-dn.net/?f=KE%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20mv%5E2)
now here we know that
m = 2 kg
v = 1 m/s
so from the above equation we have
![KE = \frac{1}{2}(2)(1^2)](https://tex.z-dn.net/?f=KE%20%3D%20%5Cfrac%7B1%7D%7B2%7D%282%29%281%5E2%29)
![KE = 1 J](https://tex.z-dn.net/?f=KE%20%3D%201%20J)
The correct answer is A. an increase in Earth's average surface temperature.
While all of these are aspects of global warming, option A best summarizes it.
Explanation:
We have,
Mass of an object is 0.5 kg
Force constant of the spring is 157 N/m
The object is released from rest when the spring is compressed 0.19 m.
(A) The force acting on the object is given by :
F = kx
![F=157\times 0.19\\\\F=29.83\ N](https://tex.z-dn.net/?f=F%3D157%5Ctimes%200.19%5C%5C%5C%5CF%3D29.83%5C%20N)
(B) The force is simply given by :
F = ma
a is acceleration at that instant
![a=\dfrac{F}{m}\\\\a=\dfrac{29.83}{0.5}\\\\a=59.66\ m/s^2](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7BF%7D%7Bm%7D%5C%5C%5C%5Ca%3D%5Cdfrac%7B29.83%7D%7B0.5%7D%5C%5C%5C%5Ca%3D59.66%5C%20m%2Fs%5E2)
The two components of projectile motion include the following:
<h3>What is a Projectile?</h3>
This is defined as a missile propelled by the application of an external force and allowed to move freely under the influence of gravity and air resistance.
The equation for Horizontal motion Vx = V * cos(α)
Vertical velocity component: Vy = V * sin(α)
