velocity of the ball is given as

now we have

Part a)
We need to find velocity of ball with respect to Juan
so it is given as



magnitude of the speed is given as


Part b)

East of South
Answer:
A steady decline in driving ability
Explanation:
Alcohol consumption impairs the functioning of the central nervous system. The impairment can range from mood improvement to unconsciousness. As the blood alcohol level (BAL) rises the impairment gets severe. Driving is a complex task that requires the central nervous system to function properly.
Any impairment to the central nervous system leads to a decline in driving activity.
Answer:
137.2J
Explanation:
Ep= mgh
Given,
and we know, g = 9.81 N/kg
Ep= 2 × 9.81 × 7
Ep= 137.2J
The solution for this problem is:
For 1st minimum, let m be equal to 1.
d = slit width
D = screen distance.
Θ = arcsin (m * lambda/ (d))
= 0.13934 rad, 7.9836 deg
y = D*tan (Θ)
y = 6.50 * tan (7.9836)
= 0.91161 m is the distance from the central maximum to the first-order minimum
This question is incomplete; here is the complete question:
A phoneme is the largest unit of sound in a word. Please select the best answer from the choices provided
A. T
B. F
The correct answer to this question is F (False)
Explanation:
The word "phoneme" is used to refer to the minimal unit of sound in words, and therefore in language. For example, the first phoneme in the word "man" is "m". These units of sound are essential in language because they make each word unique in meaning and sound. For example, "fan" and "man" are different due to the phonemes "m" and "f". According to this, the phone is not the largest unit of sound but the smallest unit.
