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 race car circles 10 times around a circle with a diameter of 7 km track in 50 min. Using SI
vodka [1.7K]

Average Speed = 23.33 m/s

<u>Explanation:</u>

Given:

Diameter = 7 km

So, to find the distance, we need to multiply it by 10 as the race car circles 10 times round this 7 km track.

Distance = 7 × 10 = 70 Km or 70,000 m

Time        = 50 mins

                = 50 × 60 = 3000 s

Now, in order to find the average speed for 10 cycles, we use the formula:

Speed = \frac {Distance} {Time}

So by substituting the above values in the given formula, we get:

Speed = \frac {70,000} {3000}

Speed = 23.33 m/s

(a) The stick is supported by a sharp point at the middle. On the left side, a weight of 100 g is suspended at 40 cm from the mi
Jet001 [13]

Answer:

20cm

Explanation:

Hello!

remember that the condition for a body to be at rest is that the sum of its moments and its forces be zero,

To solve this problem you must draw the free body diagram of the stick (attached image) and sum up moments at point 0 (where the sharp is located), which results in the following equation

(100g)(40cm)=x(200g)

X=\frac{(100)(40)}{(200)} =20cm

Bad White [126]

Answer: 5.96m/s

Explanation:

Given the following :

Mass of car (m) = 1500kg

Velocity (V) = 5.25m/s

Forward force of engine = 1250N

Diatance moved = 4.8m

Final Velocity =?

Final kinetic energy = Initial kinetic energy + work done by engine

Initial kinetic energy = 0.5 × mass × velocity^2

Initial kinetic energy = 0.5 × 1500 × 5.25^2

Initial kinetic energy = 20671.875 J

Work done by engine = Force × distance

Work done by engine = 1250 × 4.8 = 6000J

Final kinetic energy = (20671.875 + 6000) J

= 26671.875 J

From kinetic energy = 0.5mv^2

26671.875 = 1/2 × 1500 × v^2

53343.75 = 1500v^2

v^2 = 35.5625

v = sqrt(35.5625)

v = 5.96m/s
