Microwaves have a higher frequency than radio waves, so why is it that they don't travel faster?

Physics
1 answer:
Lubov Fominskaja [6]3 years ago
4 0

Answer: Energy requirement or consumption also increases as frequency goes higher. Hence, those low-frequency to mid-frequency waves are commonly referred to as radio waves and essentially, they have longer wavelengths. On the other hand, microwaves have higher frequencies and shorter wavelengths.

Explanation: therefore that's why they don't travel faster.

1 kg of aluminum requires 887 J (Joule) to raise its temperature by 1 K (Kelvin). The specific heat of aluminum is expressed as
zavuch27 [327]

Answer:

887 J

Explanation:

the specific heat of  a material is defined as the amount of heat energy required to raise the temperature of the substance by 1 K of mass 1 kg. So, the specific heat of the aluminium, c = 887 J/kg K

mass of aluminium, m = 100 g = 0.1 kg

T1 = - 9° C

T2 = 1° C

ΔT = 1 + 9 = 10° C

The amount of heat required

H = m x c x ΔT

H = 0.1 x 887 x 10 = 887 J

A baseball has mass 0.145 kg.
Vesnalui [34]

Answer:

a).p=15.67kg*m/s

b). F=7.83N

Explanation:

change in momentum is the subtraction from "after momentum" of the "before momentum"  as momentum is a vector quantity this is a vector subtraction.

initial momentum of ball

m1v1 = (0.145)(44.0) = 6.38 kg-m/s

after momentum

m1v2 = (0.145)(64.0) = 9.28 kg-m/s

since these momentums are 180° opposite one must be called negative so their difference

6.38+9.28= 15.67 kg-m/s

change in momentum = 15.67 kg-m/s ANS a1

Impulse = change in momenutm = 15.67 ANS a2

b)

Impulse =Favg*t

I=(2.00)Favg

Impulse from (a2) = 15.67  

Favg = 15.67/2.00 =

F= 7.83 N
