A woman throws a baseball straight up into the air. what is the baseball's acceleration at its highest point?

Physics
1 answer:
AleksandrR [38]3 years ago
5 0
After the ball leaves the woman's hand, the only relevant force acting on the ball is the gravity, which produces an acceleration of a=g=9.81 m/s^2 on the baseball, directed downward. 
Gravity acts on the ball for the whole duration of the motion, so the acceleration of the ball is g=9.81 m/s^2 at every point of the motion, and therefore also when the baseball is at its highest point.

A ticker timer 50dots per second. When a body is pulled by a tap through the timer, the distance between the third and fourth do
Amiraneli [1.4K]

Answer:

Explanation:

Time for one dot = 1 /50 = .02 s

Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s

velocity = 3 cm / .02 = 150 cm /s

Distance between 4 th and 5 th  dot is 4 cm and time taken to travel this distance is .02 s

velocity = 4 cm / .02 = 200 cm /s

change in velocity = 200 cm/s  - 150cm/s = 50 cm /s

Time taken = .02 s

Acceleration = 50 / .02 cm/s²

= 2500 cm/s²

At what distance from a long, straight wire carrying a current of 8.7 A is the magnetic field due to the wire equal to the stren
deff fn [24]

Answer:

r= 3.2 cm

Explanation:

Given that

I= 8.7 A

B= 5.4 x 10⁻⁵ T

μo=1.25664 x 10⁻⁶

We know that magnetic filed in wire at a distance r given as

B=\dfrac{\mu_oI}{2\pi r}

r=\dfrac{\mu_oI}{2\pi B}

By putting the values

r=\dfrac{1.25664\times 10^{-6}\times 8.7}{2\times \pi \times 5.4\times 10^{-5}}\ m

r=0.032 m

r= 3.2 cm
