The given question is incomplete. The complete question is:

Estimate the volume of each ball. Use the formula $v=\frac{4\pi\times r^3}{3}$ where v is the volume and r is the radius. record the volume in table A of your student guide. The radius of the tennis ball is 2.1 cm and the radius of thr golf ball is 2.0 cm. What is the estimated volume of the table tennis ball in $cm^3
$ What is the estimated volume of the golf ball in

Answer: Volume of the tennis ball is $38.8cm^3$ and Volume of the golf ball is $33.5cm^3$

Explanation:

We have to find the Volume of tennis ball and golf ball by using the formula $v=\frac{4\pi\times r^3}{3}$

Radius of the tennis ball = 2.1 cm

Radius of the golf ball =2.0 cm.

Putting the value of radius in the formula , we get:

Volume of the tennis ball = $\frac{4\times 3.14\times (2.1cm)^3}{3}
=38.8cm^3$

Volume of the golf ball = $\frac{4\times 3.14\times (2.0cm)^3}{3}
=33.5cm^3$

Volume of the tennis ball is $38.8cm^3$ and Volume of the golf ball is $33.5cm^3$

Bats have poor vision and use echo-location to find their way.The frequency produced by bats is 100kHz. If the speed of the soun

irga5000 [103]

The distance covered is 25.9 m.

We know that the speed of sound refers to the speed with which an sound moves in an object.

Given that;

speed of sound = 345m/s

Time taken = 0.15s

We know that;

v = 2d/t

v = speed of sound

d = distance

t = time taken

vt = 2d

d = vt/2

d = 345m/s * 0.15s/2

d = 25.9 m

Now find the components NxNxN_x and NyNyN_y of N⃗ N→N_vec in the tilted coordinate system of Part B. Express your answer in term

MArishka [77]

Answer:

$N_{y} =Ncos$ Ф,

$N_{x} =-Nsin$ Ф

Explanation:

Now find the components NxNxN_x and NyNyN_y of N⃗ N→N_vec in the tilted coordinate system of Part B. Express your answer in terms of the length of the vector NNN and the angle θθtheta, with the components separated by a comma.

Vectors are quantities that have both magnitude and direction while scalar quantities have only magnitude but no direction.

This a vector quantity

from the diagram the horizontal component of the length of the vector will be

$N_{y} =Ncos$ Ф

the vertical component will be

$N_{x} =-Nsin$ Ф

this is in the opposite direction because the x can be extrapolated to the negative axis

you ride a bike for 2 hours at 25 km/hr then 3 hours at 34 km/hr. what is your average velocity (in km/hr)?

mamaluj [8]

<h3>Answer:</h3>

30.4 km/hr

<h3>Explanation:</h3>

<u>We are given</u>;

Speed in the first 2 hours as 25 km/hr
Speed in the next 3 hours as 34 km/hr

We are required to determine the average velocity in km/hr

To get the average velocity we divide total distance by total time.
Thus, we need to determine the total distance

Distance = Speed × time

Distance covered in the first 2 hours;

= 25 km/hr × 2 hours

= 50 km

Distance in the next 3 hours

= 34 km/hr × 3 hours

= 102 km

Therefore, total distance = 50 km + 102 km

= 152 km

Total time = 2 hrs + 3 hrs

= 5 hours

Therefore;

Average speed = 152 km ÷ 5 hours

= 30.4 km/hr

Thus, the average speed is 30.4 km/hr

A certain freely falling object, released from rest, requires 1.95 s to travel the last 23.5 m before it hits the ground. (a) Fi

Ratling [72]

Answer:

(a). The velocity of the object is -2.496 m/s.

(b). The total distance of the object travels during the fall is 23.80 m.

Explanation:

Given that,

Time = 1.95 s

Distance = 23.5 m

(a). We need to calculate the velocity

Using equation of motion

$s = ut+\dfrac{1}{2}gt^2$

Put the value into the formula

$-23.5=u\times1.95+\dfrac{1}{2}\times(-9.8)\times(1.95)^2$

$u=\dfrac{-23.5+4.9\times(1.95)^2}{1.95}$

$u=-2.496\ m/s$

(b). We need to calculate the total distance the object travels during the fall

Using equation of motion

$v = u+gt$

Put the value in the equation

$-2.496=0-9.8\times t$

$t =\dfrac{2.496}{9.8}$

$t=0.254\ sec$

The total time is

$t'=t+1.95$

$t'=0.254+1.95$

$t'=2.204\ sec$

We need to calculate the distance

Using equation of motion

$s = ut+\dfrac{1}{2}gt^2$

Put the value into the formula

$s=0+\dfrac{1}{2}\times9.8\times(2.204)^2$

$s=23.80\ m$

Hence, (a). The velocity of the object is -2.496 m/s.

(b). The total distance of the object travels during the fall is 23.80 m.

A one dimensional array data is declared as follows: char data[4]; the base address is 2222 and each value takes up one location

andrezito [222]

The correct answer for the address of the fourth element will be 2225.

The fourth element will be data -.

So if the data[0] element starts at 2222, and each char element takes 1 byte, then

data[0] starts at 2222

data[1] starts at 2223

data[2] starts at 2224

data[3] starts at 2225

Answer: 2225

A linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations is known as an array. Arrays use an index system that ranges from 0 to (n-1), where n is the array's size.

The array data type is a compound data type represented in the database dictionary by the number 8. Arrays are collections of elements of the same data type that are accessed via an index (attribute) number. The terms array, list, vector, and sequence are all synonymous
