This is simple question and easy to understand.
so first you use a formula to calculate frequency of the wave.
v _ stands for velocity a.k.a speed
f_ stands for frequency which you have to find.
(pronounced lemda)_ stands for wavelength.
Then you gonna place all your values according to you have in the formula as shown then solve for f.
Finally, you use the time formula
where
T_ is period a.k.a time which equal to the reciprocal of frequency or equal to 1/f.
Simply input your values according to the formula and you your answer as 0.5s
A black sweater. Why? Because black is the most absorbent color while as white is reflecting the light. Hope this helps...
<h3>Answer</h3><h3>option B</h3><h3>38 N</h3><h3>Explanation</h3>
Given that,
mass of block A = 14kg
mass of block B = 12kg
angle alpha equals = 19°
<h3>Formula to find tension in the wire connecting blocks A and B</h3>
Tension in wire connecting weight of object A and B is due to weight of block B
= mgsin19
due to slope we will take horizontal components of weight, mg
= 12(9.81)sin(19)
= 38.3
Answer:
Explanation:
Let assume that direction is positive when football travels to the player. The situation can be described properly by applying the definition of Momentum and Impulse Theorem. That is to say:
The average force needed to stop is obtained after some algebraic manipulations:
The impulse delivered to the ball is:
A thin layer of till
that blankets the landscape after a glacier melts is called ground moraine.
Ground moraines<span> <span>are
till-covered areas with irregular topography and no ridges, often forming
gently rolling hills or plains. They are accumulated at the base of the ice as
lodgment till, but may also be deposited as the glacier retreats.</span></span>
