Answer:
Explanation:
simple, just use F = ma
assume that the acceleration is any positive value <em>a</em>
The force F must accelerate both sleds
F = (2m + m)<em>a</em>
The force T must accelerate the rear sled
T = m<em>a</em>
T/F = m<em>a</em>/3m<em>a</em> = 1/3
Answer:
Explanation:
Given:
't' hour be the time taken for travel by both the vehicles and 'd' be the distance between then
then
Distance traveled by the car = 20 × t miles
and
Distance traveled by the truck = 50 × t miles
now, using the Pythagoras theorem
or
or
or
thus, the equation relating the distance 'd' with the time 't' comes as
<span>θ is the angle whose tangent is 3/0.4 = arctan (7.5) = 82.4°
(That's the angle above the horizontal. If that doesn't match
the </span><span>θ in your diagram, too bad ! For some strange reason,
I wasn't able to see your diagram.)

The electromagnetic waves are types of waves which do not require medium for them to pass through to be able to travel from one location to another. The different types of electromagnetic waves therefore vary only in their wavelength and frequency. Thus, the answer is letter B.
