Answer:
a) 37.70 m/s
b)710.6 m/s²
Explanation:
Given that ;
Mass of object = 2 kg
Radius of the motion = 2m
Frequency of motion = 3 rev/s
The formula to apply is;
v= 2πrf where v is linear speed
v = 2×π×2×3 =12π = 37.70 m/s
Centripetal acceleration is given as;
a= 4×π²×r×f²
a= 4×π²×2×3²
a=710.6 m/s²
Answer:Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance. ... Compression would force the atoms on adjacent molecules to occupy the same region of space.
Explanation:
The motion of the inferior angle of the scapula in the superior and lateral direction is called upward rotation.
<h3>What are the possible motions of the scapula?</h3>
The scapula or the shoulder blade has about six different types of motion it undergoes.
The six ways of movement of the scapula are:
- protraction,
- retraction,
- elevation,
- depression,
- upward rotation, and
- downward rotation
When the inferior angle of the scapula moves in the superior and lateral direction, the motion is called upward rotation.

F=mgsinα –F(fr)=
= mgsinα - μmgcosα
a=F/m =g(sinα – μcosα)

Answer:
Explanation:
Given
Current is flowing towards right side
Considering right side i.e. +x to be positive and direction outside the paper be +k
suppose charge is below the wire and is moving towards right
magnetic field below the wire is outside the Paper using right hand thumb rule
i.e. Force acts in Downward direction
i charge is moving towards left i.e.
towards upward direction
