Answer:

At v=10\ ms^{-1} energy of the ball will be = 500\ Joules

Step-by-step explanation:

Given:

Mass of ball =10 kg

The table for velocity vs Energy is given.

Velocity(ms^{-1})=0,2,3,6,10

Energy(Joules)=0,20,45,180,E  

Energy is in terms of velocity is given by:

E=\frac{1}{2}mv^2

where m represents mass and v represents velocity.

∴ at velocity = 10\ ms^{-1}

Energy = E=\frac{1}{2}(10)(10)^2

E=5\times100

∴ E =500\ Joules

∴ At v=10\ ms^{-1} energy of the ball will be = 500\ Joules

Determine whether the quantitative variable is discrete or continuous. Number of students in a class Is the variable discrete or
olga nikolaevna [1]

Answer:

D) The variable is discrete because it is countable.      

Step-by-step explanation:

Both discrete and continuous falls under the numeric category.

Discrete variables are the variable that are countable and cannot be expressed in decimal form.

Example: Tosses of a coin, Number of rooms in an house.

Continuous variables on the other hand cannot be counted, they are countable and can be expressed in the form of decimals. Its value can be expressed in the form of interval.

Example: Time, Length.

Now, number of students in a class is a discrete variable since students are countable and they cannot be expressed in decimal form.

So the correct option is D) The variable is discrete because it is countable.
