As two trucks approach each other, the driver of one truck blows his horn. Compared to the true frequency of the horn when the trucks are stationary, the frequency heard by the other driver will be (DOK 2) Question 6 options:

A. Lower because the distance between the two trucks is decreasing.

B. Higher because the distance between the two trucks is increasing.

C. Lower because the distance between the two trucks is increasing.

D. Higher because the distance between the two trucks is decreasing.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests
