The kinetic energy K (in joules) of a falling apple is represented by K=v22, where v is the speed of the apple (in meters per se

cond). How fast is the apple traveling when the kinetic energy is 32 joules? The apple is traveling at meters per second.

Answer: 1.455 m/s

Step-by-step explanation: k = 22v defines the motion of falling apple.

With k as kinetic energy and v as velocity.

We are to find the value of v at k = 32 joules

32 = 22v

v = 32/ 22

v = 1.455 m/s

. Over the next two days, Clinton Employment Agency is interviewing clients who wish to find jobs. On the first day, the agency
Vedmedyk [2.9K]

Answer:

4

Step-by-step explanation:

Given that :

Clients are interviewed in groups of 2 on the first day; meaning two persons at a time

Second day, clients are interviewed in groups of 4; meaning 4 persons at a time.

Therefore, if the same number of clients are to be interviewed on each day, the smallest number of clients that could be interviewed each day could be obtained by getting the Least Common Multiple of both numbers: 2 and 4

- - - - 2 - - - 4

2 - - - 1 - - - 2

2 - - - 1 - - - 1

Therefore, the Least common multiple is (2 * 2) = 4

Therefore, the smallest number of clients that could be interviewed each day is 4.

Find a right triangle that has legs with your irrational Lengths and a hypotenuse with a rational Length
cluponka [151]

gg easy


the legs of a triangle are related as a^2+b^2=c^2 wehre a, b, and c are the legs and the hypotonuse of a triangle respectively


let's find some stuff

one easy way is to find a rational value for c find values of a and b

lets pick c=5

a^2+b^2=5^2

a^2+b^2=25

now split up 25 into 2 things that don't have rational square roots

if we say a^2=19 and b^2=6 then we get

a=\sqrt{19} and b=\sqrt{6} (which are both irrational)

This relationship is given by the equation, v = gt. In this equation, g is the acceleration due to gravity, t is the number of s
DENIUS [597]

v=gt,

Initial value when time t=0, v=g*0=0.

t=0 s, v=0 m/s means that object’s initial velocity 0 m/s.

v=gt, and g is a constant g=9.8 m/s². We can write v=9.8*t.

Rate of change 9.8 means the acceleration due to gravity is 9.8 m/s².

Answer: C. The initial value is 0. That means that object’s initial velocity 0 m/s. The rate of change is 9.8. That means the acceleration due to gravity is 9.8 m/s2.

Paula, a college student, earned $3,600 one summer. During the following semester, she spent $2,500 for tuition, $650 for rent,
Softa [21]

So to get the $ spent on misc items, just add up the other expenses and subtract it from 3600:

2500+650+430=3580\\ \\ 3600-3580=\$ 20

Now to put them into fractions.

Tuition: \frac{2500}{3600}=\frac{25}{36}

Rent: \frac{650}{3600}=\frac{65}{360}

Food: \frac{430}{3600}=\frac{43}{360}

Misc: \frac{20}{3600}=\frac{1}{180}
