The stroke that begins a point in volleyball is called a serve
Answer:
Ball will not hit bell.
Explanation:
The height of the ball is modeled by the equation h(t)= -16t²+39t
We need to find if the bell is 25 ft above the ground, will it be hit by the ball.
So we need to find maximum height of the ball.
For maximum height we have
Substituting in h(t) = -16t²+39t
Maximum height reached = h(1.22) = -16 x 1.22²+39 x 1.22 = 23.77 ft
So maximum height reached is less than height of bell.
Ball will not hit bell.
Answer:
Minimum aperture diameter, B =
Given:
Altitude of airplane, l = 29 Km = 29000 m
width, d = 2.0 m
wavelength,
Solution:
By Reighley criterion, Angle of resolution is given by:
(1)
Also, separation angle or limiting angle, (2)
From eqn (1) and (2):
B = 7.96 mm
To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.
