Answer:
-50 cm^3/min
Explanation:
The volume of the lollipop is given by
where r is the radius in centimeters.
To find how fast the volume changes, we need to find the rate of change of the volume, which is given by its derivative with respect to time:
(1)
where
dr/dt is the rate of change of the radius
We know that the circumference is
and it decreases by 1 cm per minute, so
(cm/min)
from which we find dr/dt:
Substituting into (1),
(cm^3/min)
And substituting r = 5, we find the rate of change of the volume when the radius is 5 cm:
(cm^3/min)
Answer:
The scientist will be looking for the velocity of the wave in air which is equivalent to 10^7m/s
Explanation:
If an object in space is giving off a frequency of 10^13Hz and wavelength of 10^-6m then the scientist will be looking for the velocity of the object in air.
The relationship between the frequency (f) of a wave, the wavelength (¶) and the velocity of the wave in air(v) is expressed as;
v = f¶
Given f = 10^13Hz and ¶ = 10^-6m,
v = 10¹³ × 10^-6
v = 10^7 m/s
The value of the velocity of the object in space that the scientist will be looking for is 10^7m/s
Answer:
True
Explanation:
The Florida law states that a person driving an animal-drawn vehicle has the same protections that are applicable to a person driving a vehicle and the protections that are applicable to pedestrians also apply to a person riding or leading an animal upon a roadway or the shoulder of it. According to this, the answer is that the statement is true.
Deleted this answer, sorry for any inconveniences that it may have caused.
Work is done when a motion resulted from the force being done by an object. The amount of work done is calculated by multiplying the force applied and the distance traveled. It is calculated as follows:
Work = Force x distance = 280 N x 5 m = 1400 J.
