Answer:
force of 279 N
53.75 degrees from east to north
Explanation:
let net force be F , Fn - north force , Fe - east force
let the direction be α angle from east to north
Answer:
a) l = 24 cm
b) υ = 2.5 × 10⁹ Hz
Explanation:
given,
wavelength of microwave = 12 cm
length of microwave
= 2 × λ
= 2 × 12
l = 24 cm
microwave is an electromagnetic wave speed is 3 × 10⁸ m/s
v = υ λ
υ =
υ =
υ = 2.5 × 10⁹ Hz
A (b) would be 42 (c) from x to Y mark me as brainlist thanks
