Solution :
c). 
force applied by Abe
force applied by Barry
force applied by Eric
Resultant force
in the vector form can be written as :
in the vector form can be written as :
The resultant,
= 84.853 N
d). As the three forces are in equilibrium, therefore,
e). The direction of the force exerted by Eric is exactly opposite to the direction of the resultant force.
The direction of the resultant force is :
= 45° north east
The direction of the force E is 45° west or 45° south west.
Answer:
D. A low lambda, λ, and a high nu, ν
Explanation:
- Both x-rays and radio waves are electromagnetic waves that are part of the electromagnetic spectrum.
- <em><u>Radio waves have the longest wavelengths in the electromagnetic spectrum and the lowest frequency.</u></em>
- X-rays on the other hand <em><u>have a higher frequency compared to radio waves and a lower wavelength than that of the radio waves</u></em>.
- All electromagnetic waves in the electromagnetic waves travel with a speed of light, 3.0 × 10^8 m/s. They also posses energy given by the formula E = hf, where h is the plank's constant.
Answer:Gases do not conduct heat as well as liquids and are therefore good insulators. Gases consist of widely spread out particles, and it takes contact to conduct heat. ... They are insulators if they are not ionized and there are no free charged particles there that can carry electric current.
