The area of the sprinkles can be determined through the area of a circle that is pi * r^2 in which the given dimensions above are the radii, r. The second scenarios radius is only half of the original, that is 4 ft. In this case, we can compute the area of the second again. We calculate next the difference of two areas of circles.

The probability which is based on the observations of an experiment is called: A. Theoretical Probability B. Axiomatic Probabili
FromTheMoon [43]

Answer:

C. Experimental Probability

Explanation:

The empirical (or experimental) probability means the event that arise and depend how the event arise when the data is collected from an experiment in a more no of trials. It would be depend upon the direct observation. Here each and every observation in an experiment is known as trial

So the probability that depend upon the experiment observation is known as the experimental probability

Hence, the option c is correct

An ice block measuring 5cm by 5cm by 5cm has a desity of 5g/cm3. What is the mass of the ice block?
Svetradugi [14.3K]


Density = (mass) / (volume)

Volume of your block = (5cm x 5cm x 5cm) = 125 cm³

5 gm/cm³ = (mass) / (125 cm³)

Multiply each side by (125 cm³):  Mass = 625 gm

Note: 
I don't know what kind of frozen substance you're working with,
but maybe you ought to be careful handling it ... I know that's
not water ice you have there.  The density of water ice is not
5 gm/cm³.  In fact, it's a little less than 1 gm/cm³.  That's why
the ice floats in your soda.

A 4-kg ball has a momentum of 12 kg∙m/s. what is the ball's speed?
Karolina [17]
M= 4kg
v= ?
momentum = Mv
so
12kgms-¹ = 4kg×v
v= 12÷4 = 3ms-¹

mixas84 [53]

The role of thermal energy is to balance the electrical energy lost from the light bulb.

<h3>Energy conservation</h3>

The law of energy conservation states that energy can neither be created nor destroyed but can be transformed from one form to another.

<h3>Thermal energy</h3>

This is a form of energy that occurs due to rise in temperature.

The role of thermal energy is to balance the electrical energy lost from the light bulb.
