PH of 4 is Acidic and its property is to turn blue litmus red
The velocity increased from 4 m/s to 22 m/s in 3 seconds. 18 m/s in 3 seconds so the average acceleration is change in velocity divided by time. 18 m/s divided by 3 seconds = 6 m/s^2
Answer:
Current = dQ/dt
or I = dQ/dt
Where I represents current.
Which is the rate of flow of charge.
Q=4 + 2t + t²
dQ/dt = 2 + 2t --- This is the relation that gives the instantaneous current.
At time t=2sec
dQ/dt = I = 2 + 2t
= 2 + 2(2)
=2 + 4
= 6A.
Answer:
Radius of the salami = 9.9 cm
Explanation:
The formula for calculating the radius is given below:
a = v^2/r
where a represents acceleration
v represents velocity
r represents radius
As hungry mouse ran around the salami's circumference with a tangential speed of 0.17 m/s so that means velocity = 0.17 m/s.
The centripetal acceleration of the mouse = 0.29 m/s^2
putting these values in the above formula, we get
0.29 = 0.17^2 / r
After rearranging, we get,
r = 0.17^2 / 0.29
r = 0.099 m
r = 9.9 cm
so the radius of the salami = 9.9 cm
