Relating the circumference to the force applied on the balloon, make a conclusion on the relationship of force to the rate of th

natka813 [3]

At a constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

The force applied to an object can be determined by applying Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.

F = ma

where;

m is the mass of the balloon
a is the change in velocity per time

$F = m\frac{\Delta v}{t} \\\\\frac{F}{\frac{\Delta v}{t}} = m$

The mass of an object is inversely proportional to the rate of change motion of the object.

Thus, we can conclude that at constant force, the mass of the balloon is inversely proportional to the rate of change motion of the balloon.

Compare the maximum rate of heat transfer to the basal metabolic rate by converting a bmr of 88 kcal/hr into watts. what is the

elena-14-01-66 [18.8K]

Explanation :

It is given that,

BMR i.e basal metabolic rate is 88 kcal/hr. So, BMR in watts is converted by the following :

We know that, 1 kilocalorie = 4184 joules

So, $1\ kcal/h=\dfrac{1\times 4184\ J}{3600\ sec}$

$1\ kcal/h=1.16\ J/sec$

J/sec is nothing but watts.

So, $1\ kcal/h=1.16\ watts$

and $88\ kcal/h=88\times 1.16\ watts = 102.08\ watts$

So, it can be seen that the body can accommodate a modes amount of activity in hot weather but strenuous activity would increase the metabolic rate above the body's ability to remove heat.

water is pumped from a stream at the rate of 90kg every 30s and sprayed into a farm at a velocity of 15m/s. Calculate the power

nikitadnepr [17]

Answer:

340 W

Explanation:

Power = change in energy / change in time

P = ΔKE / Δt

P = ½ mv² / Δt

P = ½ (90 kg) (15 m/s)² / (30 s)

P = 337.5 W

Rounded to 2 significant figures, the power is 340 W.

Sort the following hypothetical discoveries into the appropriate bins as follows:consistent with theory: the statement describes

goblinko [34]

Here are the three observable facts that are explained by the nebular theory:
1) Planets all rotate in the same direction
2) Planets all orbit in within 6 degrees of a common plane
3) Planets within the orbit of the Asterioid Belt (terrestrial planets) are rocky while those outside it are gaseous.

Here are the missing statements and its appropriate labels:

all 6 of stars terrestrial planets have a moon as large as earth's moon - NOT CONSISTENT WITH THE THEORY

a star is surrounded by a disk of gas but has no planets - CONSISTENT WITH THE THEORY

a star has 20 planets - CONSISTENT WITH THE THEORY

a stars 5 terrestrial planets orbit in the opposite direction of its 3 jovian planets - NOT CONSISTENT WITH THE THEORY

beyond its jovian planets, a star has two ice-rich objects as large as mars - CONSISTENT WITH THE THEORY

of a stars 5 terrestrial planets, 1 has a moon as large as earth's moon - CONSISTENT WITH THE THEORY

a stars 4 jovian planets formed in its inner solar system and its 4 terrestrial planets formed farther out - NOT CONSISTENT WITH THE THEORY

a star has 9 planets, but none orbit in close to the same plane - NOT CONSISTENT WITH THE THEORY
