Answer:
The answer is a 4.2m
Explanation:
Given data
Please see attached the rough drawing for your reference.
From the drawing, you ran 18m west and 2.4m south
The displacement is
= 1.8+2.4
=4.2m
Explanation:
It is given that,
Mass of the brick, m = 1.15 kg
Radius of the circle, r = 1.44 m
The cable will break if the tension exceeds 43.0 N
Let v is the maximum sped can have at the bottom of the circle before the cable will break. At the bottom of the circle, the net force is equal to the centripetal force along with the weight of the brick. So,
![T=\dfrac{mv^2}{r}+mg](https://tex.z-dn.net/?f=T%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D%2Bmg)
![\dfrac{T}{m}-g=\dfrac{v^2}{r}](https://tex.z-dn.net/?f=%5Cdfrac%7BT%7D%7Bm%7D-g%3D%5Cdfrac%7Bv%5E2%7D%7Br%7D)
![v=\sqrt{(\dfrac{T}{m}-g)r}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%28%5Cdfrac%7BT%7D%7Bm%7D-g%29r%7D)
![v=\sqrt{(\dfrac{43}{1.15}-9.8)\times 1.44}](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%28%5Cdfrac%7B43%7D%7B1.15%7D-9.8%29%5Ctimes%201.44%7D)
v = 6.30 m/s
So, the maximum speed of the brick at the bottom of the circle before the cable will break is 6.3 m/s. Hence, this is the required solution.
Answer:
Option B is correct.
Explanation:
Potential energy or chemical potential energy is used to Cook food which is then converted into thermal energy. The type of energy used also depends upon the type of cooking appliances used.
For e.g. stove convert potential energy to thermal energy.
The glandular epithelial tissues make up the liver.
I’m gonna have to say “Ocean waves” as the answer
