Answer:
Your answer will be C. 3.8 kPa.
Answer: 18.35 m/s
Explanation:
At the highest point of trajectory, the vertical component of the velocity would be zero and the tennis ball would have horizontal component of velocity.
It is given that the initial velocity of the ball is 32 m/s and it makes 35° with the vertical. Hence the horizontal component of the velocity,
v sin θ = 32 m/s × sin 35° = 18.35 m/s
Hence, at the highest point in its trajectory, the tennis ball would be moving with the speed 18.35 m/s.
Answer:
Explanation:
Given:
cross sectional area of the bone, 
factor of up-scaling the dimensions, 
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled up area is:
![a_s=[4.8 \times 10^{-4}]\times 10^2](https://tex.z-dn.net/?f=a_s%3D%5B4.8%20%5Ctimes%2010%5E%7B-4%7D%5D%5Ctimes%2010%5E2)
Answer: By a mechanism that is not fully understood, charges in a thundercloud are separated such that the lower portion of a cloud takes on a negative charge while the upper portion is positive. In addition to the negative charge on the base of the cloud, there are small pockets of positive charge on the base.
