A small ball is attached to one end of a rigid rod with negligible mass. The ball and the rod revolve in a horizontal circle wit

h the other end of the rod at the center. The path of the ball has a constant linear speed. The force exerted by the rod is 0.5 N. The centripetal acceleration is 0.5 m/s2 . What is the mass of the ball, in kg?

Answer:

mass of the ball will be 1 kg

Explanation:

We have given force F = 0.5 N

This force must be equal to the centripetal force for the ball to revolve in the circle

So F=F_C=0.5N

Centripetal acceleration is given as a_c=0.5m/sec^2

We have to calculate the mass of the ball

We know that force is given by

F_C=ma_c

So 0.5=m\times 0.5

m = 1 kg

So mass of the ball will be 1 kg

Answer:

Corpus callosum

Explanation:

The corpus callosum is the tissue in the brain that helps in the connection between the right and left cerebral hemisphere.

The corpus callosum consists of about 200 million axons of thick nerve cells which helps in combining sensory and cognitive signals between the two hemispheres.

Almost everyone is born with this tissue because an absence of deficiency of it results in serious neurological problems such as difficulty in learning and other cognitive related diseases.

A bug is sitting on the edge of a rotating disk. At what angular velocity will the bug slide off the disk if its radius is 0.241
Ivahew [28]

Answer:

ω = 3.61 rad/sec

Explanation:

Firstly, we should know that the bug will not slip if friction can provide sufficient opposing force.

μmg = mv^2/r = mω^2r

Thus;

μg = ω^2r

ω^2 = μg/r

ω = √(μg/r)

ω = √(0.321 * 9.8)/0.241

ω = √(13.05)

= 3.61 rad/sec

ira [324]

Answer:

1.t=-1.96sec

2.H=4.8m

3.T=1.96sec

4.R=19.2m

Explanation:

u=9.8,t=?,sin theta=1

using formula t=2usintheta/g

t=2x9.8x1=19.6/10

t=1.96seconds

using formula H=u(squared)sin(squared)theta/2g

H=9.8(squared)x1(squared)/2x10

H=96x1/20

H=96/20

H=4.8m

using formula T=2usintheta/g

T=2x9.8x1/10

T=19.6/10

T=1.96sec

using the formula R=u(squared)sin2theta/g

R=9.8(squared)x2/10

R=96x2/10

R=192.08/10

R=19.2
