Acceleration toward the center of a curved path is called
Serggg [28]

Answer:

Centripetal acceleration.

Explanation:

Centripetal acceleration is a property of a body moving in a uniform circular path and it is directed radially towards the center of the circle in which body is rotating.

The force which causes this acceleration is centripetal force which is also directed towards the center of the circle and pulls the body towards its center.

It is calculated through following formula

a=v^2/r

where v is velocity and r is the radius of the circle.

He instruction booklet for your pressure cooker indicates that its highest setting is 11.1 psi . you know that standard atmosphe
blagie [28]

Given that,

Atmospheric Pressure = 14.7 psi

Cooking Pressure = 14.7 +11.1 = 25.8 psi

Take, Atmospheric Temperature = 25 °C

Cooking Temperature = ??

Since, we know that Gas equation is given by:

PV = nRT

or

P ∝ T

P1 / T1 = P2 / T2

14.7/ 25 = 25.8/ T2

T2 = 25*25.8/14.7

T2 = 43.87 °C

The cooking pressure will be 43.87 °C.

a motorboat starting from rest on a lake accelerates in a straight line at a constact rate of 3m/s square for 8sec.how far does
zimovet [89]
So check it out you can just use the old formula
v =  \frac{d}{t}
instead of deviding distance and time multiply velocity and time
so the formula would be
v \times t = d
3ms \times 8sec = 24m

A race car driver travelling at 15m*s^-1 accelerates at a constant value for 10.0s. She is now driving at a speed of 35 m*s^-1 W
cupoosta [38]

The driver speeds up with acceleration <em>a</em> so that

35 m/s = 15 m/s + <em>a</em> (10.0 s)

Solve for <em>a</em> :

20 m/s = <em>a</em> (10.0 s)

<em>a</em> = (20 m/s) / (10.0 s)

<em>a</em> = 2 m/s²
