Explanation:
Given that,
The frequency of a microwave is 6Ghz.
We know that,
We need to find the wavelength of the wave in the air.
The relation between wavelength, frequency and speed is given by :
So, the wavelength of the wave in the air is 0.05 m.
Answer:
584.32m
Explanation:
Firstly, we need to find the x and y components of each vector.
x-component for vector L=303cos205°=-274.61
y-component for vector L=303sin205°=-128.05
x-component for vector M=555cos105°=-143.64
y-component for vector M=555sin105°=536.09
Since it's the vector sum, we add the x and y components of each vector.
Resultant vector x-component -274.61+(-143.64)=-418.25
Resultant vector y-component -128.05+536.09=408.04
Now, to find the magnitude, we use the formula
sqrt(-418.25^2+408.04^2)=584.32m

Answer:
Explanation:
Earth ⇒ 9.8 m/s²
Mercury ⇒ 3.7 m/s²
Neptune ⇒ 11.2 m/s²
Uranus ⇒ 8.9 m/s²
The weight of a person can differ on different planets, but the mass stays the same. The greater the acceleration due to gravity, the greater the weight.
Arranging the planets in increasing order based on a person’s weight on the planet:
Mercury, Uranus, Earth, Neptune
