Explanation:
It is given that, a mass attached to a spring oscillates and completes 53 full cycles in 28 s. Frequency of the system is given by the number of oscillations or vibrations per second. Here, the frequency of this system is given by :
f = 1.89 Hertz
The relationship between the frequency and the time period of the spring is inverse i.e.
T = 0.52 seconds
Hence, this is the required solution.
i know for sure the water one is correct with
A. Water is important to some organisms.
I'm 50/50 about the circulatory one BUT
A. carrying heat around the body.
that is your best bet
Density is the best property to use, as while multiple different metals could create cubes with the same color, mass, or volume, no different metal could create a cube with the same mass and volume. Density is based on mass and volume, and as a result no two different metals will have the same density.
Answer:
6m/s
Explanation:
a = (v-u)/t
acceleration, a
initial velocity, u
final velocity, v
time, t
substitute values and you'll get the answer
Answer:
It is B
it is called a jumper cable because it jumps the power from one car to the other
