A volleyball dug out by the opponent popped straight up into the air. It takes 2.05 seconds for the ball to reach its peak. Dete
Archy [21]

Answer:

The height to which the ball flies is 86.6 m.

Explanation:

Given that,

Time = 2.05 sec

Acceleration = 9.8 m/s²

We need to calculate the initial velocity of volleyball

Using equation of motion

v=u-at

Where, u = initial velocity

a = acceleration

t = time

Put the value into the formula

0=u-9.8\times(2.05)^2

u=41.2\ m/s

We need to calculate the height of the the ball

Using equation of motion

v^2=u^2-2ah

Put the value into the formula

0=(41.2)^2-2\times9.8\times h

h=\dfrac{(41.2)^2}{2\times9.8}

h=86.6\ m

Hence, The height to which the ball flies is 86.6 m.

What is the prefix notation of 0.0000738?​
MrMuchimi

Answer:

7.38 × 10-5

Explanation:

All numbers in scientific notation or standard form are written in the form m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.

To convert 0.0000738 into scientific notation, follow these steps:

Move the decimal 5 times to the right in the number so that the resulting number, m = 7.38, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -5

Write in the scientific notation form, m × 10n

= 7.38 × 10-5

Therefore, the decimal number 0.0000738 written in scientific notation is 7.38 × 10-5 and it has 3 significant figures.

Answer = 7.38 × 10-5
