The answer is D. As the ambulance gets closer, the sound waves are compressed relative to the person; so the frequency increases.
He feels a 10 N to the left force moves. Yes ,he moves.
Answer: Volume = 1080m^3
Explanation:
Given that the prism has a 15 m by 18 m rectangular base and a height of 4 m
Volume is the product of length, breath and height. That is
Volume = L × B × H
Where
L = 18 m
B = 15m
H = 4m
Using the formula above gives:
Volume V = 18 × 15 × 4
V = 1080 m^3
Answer:
The correct option is;
3 times of X
Explanation:
The algebraic properties of a vector are;
Multiplicative identity for real numbers 1
1P = P for each P
Scalar associative property = r(sP) = (rs)P
Scalar distributive property (r + s)P = rP + sP
Vector distributive property r(P + Q) = rP + rQ
Additive inverse of a vector such that a vector P has an inverse -P such that we have;
P + (-P) = 0
Vector associative property (P + Q) + R = P + (Q + R)
Vector commutative property P + Q = Q + P.
