Answer:

True

Explanation:

The shutter speed has a long way in determining the quality of image captured. For a high quality image, the lens requires a low amount of light stimulating it. Cameras with slow shutter speed allow more light to get to the lens of the camera thereby producing a blurred image. 1/60 is a tolerable shutter speed if you desire a sharp image.

Have a great day ahead

A 2kg bowling ball rolls at a speed of 5 m/s on a roof of the building that is 40 meters tall. What is the kinetic energy

MrRa [10]

The kinetic energy is $\frac 1 2 m v^2$ and the height of the building doesn't matter at all.

$E = \frac 1 2 m v^2 = \frac 1 2 (2)(5)^2 = 25$ joules

A 49.0 kg wheel, essentially a thin hoop with radius 0.730 m, is rotating at 114 rev/min. It must be brought to a stop in 22.0 s

belka [17]

Explanation:

Mass of the wheel, m = 49 kg

Radius of the hoop, r = 0.73 m

Initial angular speed of the wheel, $\omega_i=114\ rev/min = 11.93\ rad/s$

Final angular speed of the wheel, $\omega_f=0$

Time, t = 22 s

(a) If I is the moment of inertia of the hoop. It is equal to,

$I=mr^2$

$I=49\times (0.73)^2$

$I=26.11\ kg-m^2$

We know that the work done is equal to change in kinetic energy.

$W=\Delta E$

$W=\dfrac{1}{2}I(\omega_f^2-\omega_i^2)$

$W=-\dfrac{1}{2}\times 26.11\times (11.93^2)$

W = -1858.05 Joules

(b) Let P is the average power. It is given by :

$P=\dfrac{W}{t}$

$P=\dfrac{1858.05\ J}{22\ s}$

P =84.45 watts

Hence, this is the required solution.

A grocery store sells 5-lb bags of mangoes. You purchase four bags over the course

sergij07 [2.7K]

Answer:

Accurate

Explanation:

Accuracy deals with the nearness of the measured values to the true value.

Precision is the ability to reproduce a certain result in a repeated fashion.

From the given masses of the 5-lb bags, we see that the mean value of the measurement is 5.1-lb
This value is very close to the original mass of the bag which is 5-lb bags.
We can say the reading is accurate

The reading is not precise because, the same weight is not reproduced. Different values of weight was reported from each of the measurement process.
