Answer:
10500 J/kg/*C
Explanation:
Quantity of heat required=mass of substance x specific heat capacity x change in temperature
Quantity of heat required=0.25 x 4200 x [30-20]
Quantity of heat required=0.25 x 4200 x 10
Quantity of heat required=10500 J/kg/*C
RAID 1 level should be choosed by the administrator.
B) RAID 1
<u>Explanation:</u>
RAID 1 is commonly utilized with a couple of plates, however, it should be possible with additional, and would indistinguishably reflect/duplicate the information similarly over all the drives in the exhibit. RAID 1 requires at least two physical drives, as information is composed at the same time to two spots.
The drives are basically identical representations of one another, so on the off chance that one drive comes up short, the other one can dominate and give access to the information that is put away on that drive. The purpose of RAID 1 is principally for repetition, as you can totally lose a drive, yet at the same time keep awake and running off the extra drive(s).
Likewise, at least two circles are required for RAID 1 equipment usage. With programming RAID 1, rather than two physical circles, information can be reflected between volumes on a solitary plate.
Answer:
The change in angular momentum is 
Explanation:
From the question we are told that
The initial angular velocity of the spinning top is 
The angular velocity after it slow down is 
The time for it to slow down is 
The rotational inertia due to friction is 
Generally the change in the angular momentum is mathematically represented as
substituting values
A muscle that assists the prime mover or helps stabilize the joint during movement would be a synergist.
Hope I helped!
