Answer:
The the magnitude of the maximum velocity and acceleration are 16.93 m/s and .
Explanation:
Given that,
Rate = 2940 rev/min
Amplitude = ±5.50 cm
(a). We need to calculate the magnitude of the maximum velocity
Using formula of maximum velocity
Where, A = amplitude
Put the value into the formula
(b). We need to calculate the maximum acceleration
Using formula of maximum acceleration
Hence, The the magnitude of the maximum velocity and acceleration are 16.93 m/s and .
Answer:
Explanation:
Actual weight, Wo = 5 N
Apparent weight, W = 4.5 N
density of water = 1 g/cm^3 = 1000 kg/m^3
density of gold, = 19.32 g/cm^3 = 19.32 x 1000 kg/m^3
Buoyant force = Actual weight - Apparent weight
Volume x density of water x g = 5 - 4.5
V x 1000 x 9.8 = 0.5
V = 5.1 x 10^-6 m^3
Weight of gold = Volume of gold x density of gold x gravity
W' = 5.1 x 10^-6 x 19.32 x 1000 x 9.8 = 0.966 N
As W' is less than W so, it is not pure gold.
Newton’s third law is a force is a push or pull that acts upon an object as a result of another object.. A shot gun when fired pulls back when a force (you pulling the trigger) is acted upon it. This is how it relates. A rifle has less kick than a shot gun because the rifle is smaller and has less of a force than a shot gun.
Synoptic chart or map is the one that shows the meteorological conditions over an extended region for the particular time period. The other names for synoptic chart are, synoptic scale, large scale or cyclonic scale.
