Explanation:
weight of water displaced=weight of sphere,
Since, plastic sphere floats in water with 50.0% of its volume submerged
so, water=2 sphere,
so sphere's density = 1/2 of water's density
Now, weight of glycerin displaced=weight of sphere,
Also given This same sphere floats in glycerin with 40.0% of its volume submerged.
so glycerin =2.5 sphere,
so sphere's density = .4 of glycerin's = 1/2 of water's.
So glycerin = 1.25 water
A. When your fire a bullet into the air, it typically takes between 20 and 90 second for it to come down,depending on the angle it was fired at,its muzzle velocity and caliber.
Explanation:
Yes, in order to determine whether two geometric figures are identical or not we tend to rotate one of the figure clockwise or anti clock wise mentally. However, in clockwise rotation larger the angel more will be the time taken for instance, it will take longer to rotate 120° than to rotate 40°. Whereas in anti clockwise ration it will be vice versa.
Answer:
You don't have to take my word on this, but given that there is less wax on A after heating, it sent the most heat into the wax balls therefore it is a better conductor if heat
The magnitude of velocity for this car is equal to 1.5 m/s.
<u>Given the following data:</u>
- Momentum of car = 3,000 kgm/s.
To calculate the magnitude of velocity for this car:
<h3>What is momentum?</h3>
In Science, momentum simply means a multiplication of the mass of an object and its velocity.
Mathematically, momentum is giving by the formula;

Making velocity the subject of formula, we have:

Substituting the given parameters into the formula, we have;

Velocity = 1.5 m/s.
