matter is a solid liquid or gas , a atom is a basic unit of a chemical element and a molecule is a group of atoms together
Answer:
x = 0.327 m
Explanation:
Block 2 of mass 1.00 kg is at rest
spring constant = 200 N/m
Block 1 of mass 2 kg moving at 4 m/s
m₁ v₁ = (m₁ + m₂)V
2 x 4 = (2 + 1) V
V = 2.67 m/s
loss of kinetic energy = gain elastic potential energy
x = 0.327 m
hence, the spring compressed distance is equal to x = 0.327 m
The rotational kinematics allows finding that the response for the time to reach the washing speed is
t = 4.26 s
Kinematics studies the motion of bodies, in the special case that the motion is circular is called rotational kinematics.
θ = w₀ t + ½ α t²
Where θ is the angle, w₀ are the initial angular velocity, α is the angular acceleration and t is the time
Rotational kinematics is written in units of radians, therefore all magnitudes must be reduced,
θ = 6 rev ( ) = 12π rad
In this case the washing machine starts from rest, therefore the initial rotational velocity is zero
θ = ½ α t²
t =
t =
t = 4.26 s
In conclusion using rotational kinematics we can find that the answer for the time to reach the washing speed is
t = 4.26 s

v = 200/19.3
Answer:
The value is
Explanation:
From the question we are told that
The depth at which the bubble is released is
The volume of the air bubble is
Generally from the ideal gas law
Given that n , R , T are constant we have that
So
Here is the pressure of the bubble at the depth where it is released which i mathematically represented as
Here is the atmospheric pressure with value
and is the pressure due to the depth which is mathematically represented as
So
=>
Here is the density of pure water with value
is the volume of the bubble at the depth where it is released
is the pressure of the bubble at the surface which is equivalent to the atmospheric temperature
is the volume of the bubble at the surface
So
=>
=>
=>
