Initial speed = 2√10 m/s
<h3>Further explanation </h3>
Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration
An equation of uniformly accelerated motion
V = vo + at
Vt² = vo² + 2a (x-xo)
x = distance on t
vo / vi = initial speed
vt / vf = speed on t / final speed
a = acceleration
vf=20 m/s
d = 60 m
a = 3 m/s²
Another name for these two words is "constant" and you want to have a "constant", because you want something to compare your experimental group to, to see whether data had changed or not. So you have placebos or a double- blind to compare your experimental group to it and also so you know you don't have a bias or anything in the study.
Answer:
While self-gravity pulls the star inward and tries to make it collapse, thermal pressure (heat created by fusion) pushes outward. These two forces cancel each other out in a main sequence star, thus making it stable.
Explanation:
Radiation can carry thermal energy.
Answer:
The magnitude of Resultant force is F = 7.21-lbs
Explanation:
Two forces acting on an object which are named as F1 and F2.
The angle formed by the forces are 60-degrees
F1 = 6-lbs , F2 = 8-lbs
theeta = 60°
F = √F1²+F2²-2(F1)(F2)cos(theeta)
F = √(6)²+(8)²-2(6)(8)cos(60)
F = √36+64-(96)cos(60)
F = 7.21-lbs
where,
F1 = magnitude of force 1
F2 = magnitude of force 2
theeta = angle formed by forces
