Answer:

0.15N

Step-by-step explanation:

Given data

Mass= 0.0056kg

distance=  4.85m

Velocity= 11.4m/s

The expression for the force is

F= mv^2/r

substitute

F=  0.0056* 11.4^2/4.85

F=  0.0056*129.96/4.85

F= 0.727776/4.85

F= 0.15N

Hence the force is 0.15N

What is an equation of the line that passes through the points <br> (8,2) and <br> (7,1)?
gogolik [260]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(8,2)....x1 = 8 and y1 = 2

(7,1)....x2 = 7 and y2 = 1

now we sub

slope = (1 - 2) / (7 - 8) = -1/-1 = 1

y = mx + b

slope(m) = 1

use either of ur points...I will use (8,2)...x = 8 and y = 2

now we sub and find b, the y intercept

2 = 1(8) + b

2 = 8 + b

2 - 8 = b

-6 = b

so ur equation is : y = 1x - 6....or just y = x - 6 <===

A fire burned a square - shaped forest 14mi on a side the area is ?
Tpy6a [65]
A square has all sides of the same length. This means that the length and width are both 14 miles. The area of a square is Length times width, or 14 times 14. This comes out to be 196 miles squared

Lara makes 2 cakes in 3/4 mins. If she do 4 cakes then how many min did she take to do?
Julli [10]
She took 1 1/2 minutes to make 4 cakes. You can multiply 3/4 by 2. You get 6/4 = 1 2/4 = 1 1/2. You can also add 3/4 + 3/4. That is 6/4 = 1 2/4 = 1 1/2.
Hope it helped.
