Net force = 129.4, Force as multiple of weight of her hand = 18.84
Total body weight = 56.0 kg ;
no. of turns = 2.5/second ;
hand to hand distance = 1.5m ;
weight of hand = 1.25% of body weight ;
mass of hand = *56 = 0.7kg ;
radius = d/2 = 1.5/2 = 0.75m ;
Now we need to find velocity, as we know that velocity can be calculated by dividing distance by time
v = d/t = = 11.775 m/s or 12 m/s;
The formula to calculate force is given as
F = mv²/r = (0.7*11.775²)/0.75 = 129.4 N
To calculate force as multiple of weight on her hand, we need to calculate the gravitational force W on her hand first.
W = gm = 9.81 * 0.7 = 6.867 N
Now the wieght on her hand can be represented by
= 129.4 / 6.867 = 18.84
Under normal conditions of temperature and pressure, the gaseous state of a liquid is called _______. A. vapor
The gaseous state of a liquid is called as vapor under normal conditions of temperature and pressure.
Answer: Option A
Vapor is a form of substance floating in air where increasing or decreasing the temperature and pressure changes the state of the substance into gas or liquid.
For example : consider water where heating it to the boiling point makes it as water vapor and reducing its temperature makes it as ice.
Why isn't the earth the same distance from sun all year long?
Earth's orbit is elliptical
The earth's orbit is not a straight circle and the sun is not in the very center of it. The orbit is more of a wonky oval with the sun closer to one side of it than the other causing the earth's distance from the sun to vary throughout the year.
Because the planets (and everything else in the solar system) don't travel in circular orbits with the sun at the center of the circle.
They travel in elliptical orbits, with the sun at one focus of the ellipse.
Different points on the ellipse have different distances from the focus where the sun is.

What do we mean by primitive material? How can we tell if a meteorite is primitive?
Primitive material was formed in the early stage of the solar system, before planets cooled off enough to differentiate elements of different density. It was not subject to great heat or pressure after it formed.
We can identify primitive meteorites by their composition, primitive meteorites are usually undifferentiated stones, with some metallic grains mixed in. Some primitive meteorites are darker, carbonaceous stones.
