Answer:
Explanation:
For the cat to stay in place on the merry go round without sliding the magnitude of maximum static friction must be equal to magnitude of centripetal force
Where the r is the radius of merry-go-round and v is the tangential speed
but
So we have
Substitute the given values
So
<h3>Answer</h3>
(A) Resistance is directly related to length.
<h3>Explanation</h3>
Formula for resistance
R = p(length) / A
where R = resistance
p = resistivity(material of wire)
A = cross sectional area
So it can be seen that resistance depends upon 3 factors that are length of wire , resistivity of wire and the cross sectional area of the wire.
If two of the factors, resistivity and cross sectional area, are kept constant then the resistance is directly proportional to the length of wire.
<h3> R ∝ length</h3>
This means that the resistance of the wire increases with the increase in length of the wire and decreases with the decrease of length of the wire.
Answer:
The component form will be;
In the x-axis = 121.73 due west
In the y-axis = 690.35 due south

Answer:
The answer is 15000kgms^-2
Explanation:
Actually here we are using the formula F=ma
Answer:
the release will be at 3.266 m distance
Explanation:
mass = 1 Kg
spring constant (k) = 800 N/m
initial compression = 0.20 m
θ = 30⁰
hence the release will be at 3.266 m distance.
