Answer:
The centripetal force acting on the hammer is 57.14 N.
Explanation:
Given that,
Mass of the hammer, m = 7 kg
Length of the chain, l = 1.3 m
The hammer makes one revolution in 1 s. The length of the chain will be the radius of the circular path. So, the formula of centripetal force is given by :
Here,
So, the centripetal force acting on the hammer is 57.14 N. Hence, this is the required solution.
When supernova explodes
because of the collapsing cores, the core itself will become a neutron star or
a white dwarf without undergoing any kind of explosive transformation. The white
dwarf stars can also become supernova if they orbit another star in a binary
system and steal material from their companion. In addition, the end state of a
star, whether it will explode as a supernova become a black hole.
Answer:
165 degrees F (high)
Explanation:
to destroy the most heat pathogens found in raw poultry
Answer:
Explanation:
Average speed is always: ( total distance traveled ) / ( time elapsed )
The time for the walk is +150+%2B+30+%2B+140+=+320+ s
The distance traveled is +160+%2B+210+=+370+ m
( total distance traveled ) / ( time elapsed ) = +370+%2F+320+=+1.156+ m/s
