Answer:

To find the area of the rectangular sides, use the formula A = lw

To find the area of the triangular faces, use the formula A = 1/2bh,

Step-by-step explanation:

1st formula where A = area, l = length, and h = height.

2nd formula where A = area, b = base, and h = height.

To find the surface area of the triangular prisms, you need to use the following formula: A=2AB(a+b+c)h.

To find AB you use this formula:AB= square root of (s(s﹣a)(s﹣b)(s﹣c))

Substitute your values and you will be able to find your surface area.

If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s, what is the acceleration of the objec

SVETLANKA909090 [29]

Answer

Find out the what is the acceleration of the object .

To prove

Formula

$Acceleration = \frac{Final\ velocity - Intial\ velocity}{Time }$

Where

t = the time in which the change occurs

As given

If the velocity of an object changes from 65 m/s to 98 m/s during a time interval of 12 s .

Final velocity = 98 m/s

Intial velocity = 65 m/s

Time = 12 s

Put in the formula

$Acceleration = \frac{98 - 65}{12}$

$Acceleration = \frac{33}{12}$

Acceleration = 2 .75 m/s ²

Option (A) is correct .

a body starts its motion with speed of 10m/s and accelerates for 10s with 10 m/s. what will be the distance covered by the body

pochemuha

Answer:

600 m.

Step-by-step explanation:

We can use one of the equations of motion under constant acceleration. The one we want here is s = ut + 0.5at^2, where s = distance travelled, u = initial speed, a = acceleration and t = time.

We have: s = 10*10 + 1/2 * 10 * 10^2

= 100 + 500

= 600 m. (answer)
