Answer:
10°C
Explanation:
To convert °F to °C, we use the formula:
°C = (°F - 32) * ( 5/9)
So, to convert 50°F to the equivalent in °C, we can proceed as follows:
°C = ( 50 - 32 ) * (5/9)
°C = ( 18 ) * (5/9), which is, approximately,
°C = 9.999999999... ≈ 10 (5/9 ≈0.555555...)
So, 50°F is equivalent to 10°C.
Answer:
The answer is D. 5390
Explanation:
A kilogram to newton unit is 1 kg to 9.80665 newtons
If you do 550 times 9.80665 you get roughly 5393.6575 which is the closest to 5390
Answer:
Explanation:
Given:
- frequency of the broadcast,
- we have the speed of the radiation equal to the speed of light,
The broadcast waves are the electromagnetic waves but it can travel only upto a hundred kilometers without any loss of information carried by it.
<u>The relation between the frequency and the wavelength:</u>
Answer:
Explanation:
a ) maximum friction possible
= .3 x 30 x 9.8
= 88.2 N
It is friction force which creates acceleration in 30 kg packing case.
Friction force F
F = ma
= 30 x 2.51
= 75.3 N
It will be in north direction , the direction of acceleration.
b ) F = ma
= 30 x 3.63
= 108.9 N
But maximum friction force is 75.3 N , so load will start slipping northward. so friction force will be acting southward.
Friction force = .2 x 30 x 9.8 ( coefficient of kinetic friction applies )
= 58.8 N
towards south .
