The correct answer is the wavelength of the light. Good luck m8
Answer:
Potential Energy at the greatest point = 37.5 J
Explanation:
Given :
Mass is 750 g
In term of kg :
Mass is 0.75 kg .
Velocity ( v ) = 10 m / sec
We have formula for kinetic energy :
K.E. = 1 / 2 m v²
Putting values now :
K.E. = 1 / 2 × 0.75 × 10 × 10
K.E. = 1 / 2 × 75 J
K.E. = 37.5 J
Since K.E . = P.E.
Thus potential energy of stone is 37.5 J .
Answer:
b) 188 N
c) 275 N
Explanation:
Draw a free body diagram of the box. There are four forces:
Applied force F at an angle θ
Weight mg pulling down
Normal force Fn pushing up
Friction force Ff pushing left
(b)
Sum of the forces in the x direction:
∑F = ma
F cos θ − Ff = 0
Ff = F cos θ
Ff = 200 cos 20°
Ff = 188 N
(c)
Sum of the forces in the y direction:
∑F = ma
F sin θ + Fn − mg = 0
Fn = mg − F sin θ
Fn = (35)(9.8) − 200 sin 20°
Fn = 275 N
Answer:
24 metre
Explanation:
From the available information in this question,
The swarm of bees moves at 0.20 per second
If it moves at
O.20 = 1 second,
We have a minute to be = 60 seconds
So in one 1 minute the velocity =
0.20 x 60 seconds
= 12 meters
The 2 minutes = 60 seconds x 2
2 minutes = 120 seconds
120 x 0.20 = 24 meters
So in 2 minutes these swarm of bees are going to travel a distance of 24 metres
