It means the speed of the object is increasing
and
there is a positive acceleration in the direction of the velocity
hence
there is a force acting on the object, in the direction of the velocity

A person's prescription for his new bifocal eyeglasses calls for a refractive power of -0.0675 diopters in the distance-vision p
gulaghasi [49]

Answer:

Far point of the eye is 14.83 m

Far point of the eye is 1.27 m

Explanation:

\frac{1}{f}=-0.0675

Object distance = u

Image distance = v

Lens equation

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}-\frac{1}{u}=\frac{1}{v}\\\Rightarrow \frac{1}{v}=-0.0675-\frac{1}{\infty}\\\Rightarrow \frac{1}{v}=\frac{1}{-0.0675}\\\Rightarrow v=-14.81\ m

Far point

|v|+\text{Position from eye}\\ =|-14.81|+0.02\\ =14.83\ m

Far point of the eye is 14.83 m

Object distance = u = 2.5-0.02 = 2.48 m

\frac{1}{f}=1.2

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}\\\Rightarrow \frac{1}{f}-\frac{1}{u}=\frac{1}{v}\\\Rightarrow \frac{1}{v}=1.2-\frac{1}{2.48}\\\Rightarrow v=1.25\ m

Near point

|v|+\text{Position from eye}\\= |1.25|+0.02\\ =1.27\ m

Far point of the eye is 1.27 m

If a riding lawnmower engine exerts 19 hp in one minute to move the mower, how much work is done? (Hint convert: 1 watt equals 0
charle [14.2K]

Answer:

Work done = 838470 Joules.

Explanation:

Given the following data;

Power = 19 hp

Time = 1 minute to seconds = 60 seconds.

Next, we would convert the unit of power in "hp" to "Watt."

1 Watt = 0.00135962 horsepower

x Watt = 19 horsepower

Cross-multiplying, we have;

19 = 0.00135962x

x = 19/0.00135962

x = 13974.5 Watts.

Now, to find the work done in moving the mower;

Work done = power * time

Substituting into the formula, we have;

Work done = 13974.5 * 60

Work done = 838470 Joules.

To properly record a measurements, you must record which of the following?
serg [7]
I'm not too sure about this but unit is definitely one of the answers. If "number" refers to (for example) the "6" in 6 inches then it should also count. I think "symbol" could also just be unit so I'm not sure about that.
