Because it does not produce waste, thus it doesn't harm the environment. also renewable sources are infinite.
Answer:
W = 222 N.
Explanation:
The qiestion says" If the acceleration of gravity on the surface of the planet Mercury is 3.7 m / s2, then what would be the weight of a person with mass 60 kg on its surface?
"
Mass of the person, m = 60 kg
The acceleration due to gravity on the surface of gravity is 3.7 m/s²
We need to find the weight of a person on the surface of Mercury.
Weight of an object is given by :
W = mg
So,
W = 60 kg × 3.7 m/s²
W = 222 N
Hence, the person will weigh 2222 N on the surface of Moon.
M = 45.0 g in Kg 0.045 Kg
speed = 75.0 m/sec
Δp = m * speed
Δp = 0.045* 75.0
Δp = 3.375 kg.m/s
hope this helps!
Answer:a
Explanation:I just took the quiz and got it right lol
Answer:
The wavelength in air and in tissue are 
and 
.
Explanation:
Given that,
Frequency = 3.78 MHz
We need to calculate the wavelength in air
Using formula of wavelength
Where, v = speed of sound in air
f = frequency
Put the value into the formula
We need to calculate the wavelength in tissue
Using formula of wavelength
Where, v = speed of sound in tissue
f = frequency
Put the value into the formula
Hence, The wavelength in air and in tissue are and .
