Answer:
Explanation:
If the dragster attains the speed equal to that of the car which is moving with constant velocity of v₀ , before the two close in contact with each othe , there will not be collision .
So the dragster starting from rest , must attain the velocity v₀ in the maximum time given that is tmax .
v = u + a t
v₀ = 0 + a tmax
tmax = v₀ / a
The value of tmax is v₀ / a .
From the above reaction the temperature of the surroundings will increase.
1,2,3,4 is the answer, your welcomethe answer is movement !
Answer: 186411.3 mi/s
Explanation:
We have the speed of light in units of meters per second (
):
And we need to express it in miles per second (
), knowing (
), then:
Answer:
Explanation:
Given that,
A sphere has a volume of V and a radius r
Volume of sphere cam be determine using the formula
V = 4/3 πr³
V = 4πr³ / 3.
If the radius of the sphere is increasing by
dr / dt = 5cm / min
How fast is the volume increasing when r = 10cm
dV / dt =?
From V = 4πr³ / 3
We can calculate dV/dr
dV/dr = 12πr² / 3
dV/dr = 4πr²
Then,
We want to find dV/dt
Using chain rule
dV/dt = dV/dr × dr / dt
dV/dt = 4πr² × 5
dV/dt = 20πr²
So, at r = 10
dV/dt { 20π × 10²
dV/dt = 6283.19 cm/min
The rate at which the volume increase is 6283.19 cm/min
