Answer:
e. half of Bonnie's.
Explanation:
Jill and Bonnie move in a circular path with the same angular speed of the merry-go-round.
The tangential velocity of the body is calculated as follows:
v = ω*R
where:
v is the tangential velocity or linear velocity (m /s)
ω is the angular speed (rad/s)
R is radius where the body is located from the center of the circular path
Data
1 rev = 2π rad
ω = 1 rev/2s = 2π rad/2s = π rad/s
R : radio of the merry-go-round
Bonnie's linear velocity (vB)
vB = ω*R = π*R (m/s)
Jill's linear velocity (vJ)
vJ = ω*(R
/2) = (1/2 )(π*R) (m/s)
Answer:
a) 104
b) 106
c) 884 mA
Explanation:
The ratio of the transformer is given by:
We need to know the current in the primary in order to obtain the power applied.
The current rating of the fuse is the current on the primary, 884mA as we calculated before in order to obtain the power.
Answer:
Radiative transport
Explanation:
Radiative transportation takes place extensively in the core of the sun. It produces solar energy which are emitted outward from the core of the sun, and it comprises more than 70% of the sun's heat energy. At the core of the sun, the process of nuclear fusion takes where the hydrogen atoms combines with one another, and forms helium, and during this process, it releases a large amount of energy. The photons continuously interacts with the ions (or atoms) and releases this energy to the particles and the excited particles converts the excess amount of energy into another photon which are carried outward by the process of radiative transport.
Answer: Option (a) is the correct answer.
Explanation:
Resources which are created by human beings are known as man-made resources.
For example, glass, rayon, nylon etc are all man-made resources.
Whereas resources which are naturally created are known as natural resources.
For example, wind, air, water etc are all natural resources.
Thus, we can conclude that out of the given options time is not a natural resource.
