Answer:
The wavelength of this wave is 1.01 meters.
Explanation:
The variation in the pressure of helium gas, measured from its equilibrium value, is given by :
..............(1)
The general equation is given by :
...........(2)
On comparing equation (1) and (2) :
Since,
So, the wavelength of this wave is 1.01 meters. Hence, this is the required solution.
Answer:
For uniform acceleration
a = (v2 - v1) /t = 2.5 acceleration is constant 2.5
v2 = 2.5 * 4 v1 = 0 at t = 0
v2 = 2.5 m/s^2 * 4 s = 10 m/s
Answer:
Where m is Ashley's mass and M is Miranda mass, in kg.
Explanation:
Let m be Ashley's mass and M be Miranda mass, in kg.
By the law of momentum conservation, after the hop on, we have the following momentum equation:
mv + MV = (m + M)S
where v = 3m/s is Ashley speed before the hop on, V = 4.2 m/s is Miranda's speed before the hop on. And S is their speed after
Answer:
a) d = 6.0 m
Explanation:
Since car is accelerating at uniform rate then here we can say that the distance moved by the car with uniform acceleration is given as
here we know that
now we will have
Answer:
85 N
Explanation:
Given that crate mass = 20kg
Distance = 6m
Time = 3 seconds
Coefficient of kinetic friction = 0.3
We begin by calculating for acceleration
Which was gotten as 1.33 m/s sq
