Answer:
P = 15.90 W
Explanation:
given,
speed of conveyor belt = 0.56 m/s
conveyor belt move up to = 2 m
angle made with the horizontal = 15°
mass of the box = 2.1 kg
rate is the force of the conveyor belt doing work on the box as the box moves up
P = F v cos ∅
P = 3 × 9.8 × 0.56 × cos 15°
P = 15.90 W
Because the gravitational field strength on the moon (1.6N/kg)is smaller than the gravitational field strength on the earth (9.8N/kg). Weight= mass×gravitational field strength. Your mass is the same but as g is smaller, your weight decreases. weight is the gravitational force, the downwards force towards the centre of the planet, and as it will be smaller on the moon, the force of attraction between the moon and you is smalller so when you jumb you will reach a higher point above the ground than when you jumb on the earth. Basically the moon 'pulls' you less than the earth.
Answer:
26.5m/s²
Explanation:
Given parameters:
Tangential velocity of the object = 23m/s
Radius of track = 20m
Unknown:
Acceleration = ?
Solution:
The acceleration of the body is its centripetal acceleration. It is given by;
a =
v is the tangential velocity
r is the
a =
= 26.5m/s²
Answer:
The angle of the fourth order maximum is 1.027 degrees.
Explanation:
It is given that,
Wavelength of red laser, 
Slit separation, 
We need to find the angle of the fourth order maximum. For maximum, the equation is given by :



So, the angle of the fourth order maximum is 1.027 degrees. Hence, this is the required solution.
