To determine athletes body fat, there are weighed first in air and then again while they are completely underwater. It is found
rodikova [14]

Answer:

1065 Kgm-3

Explanation:

We can determine the relative density of the athlete from the formula;

Relative density of athlete = weight of athlete in air/upthrust on athlete

Since weight of athlete in air= 690 N

Weight of athlete in water = 42 N

Upthrust on athlete= weight in air - weight in water

Upthrust on athlete= 690 N - 42 N = 648 N

Relative density of athlete= 690 N / 648 N

Relative density of athlete= 1.065

Therefore, average density of the athlete= relative density × density of water = 1.065 × 1000 Kgm-3 = 1065 Kgm-3

what is the momentum of a child and a wagon if the total mass of the child and wagon is 22kg and the velocity is 1.5m/s?
antoniya [11.8K]

Answer:

33 kg m/s

Explanation:

The momentum of an object is given by:

p=mv

where

m is the mass of the object

v is the velocity of the object

In this problem, the total mass of the child and the wagon is m =22 kg, while the velocity is v = 1.5 m/s, therefore the momentum is

p=mv=(22 kg)(1.5 m/s)=33 kg m/s

A step up transformer has a primary coil with 100 turns and a secondary coil with 25 turns if the input voltage in the primary c
Montano1993 [528]
The turn and voltage ratio of a transformer can be simply expressed by the equation:
Ns/Np = Vs/Vp; where N is the number of turns and V is the voltage.

Plugging in the given values, we have:
25 turns / 100 turns = Vs / 40 volts
Vs = 40 volts (25 turns/100 turns)
Vs = 10 volts

The answer is D.
