Many television sets show 25 images, called 'frames, each second. What is the time interval between one

Physics

Firlakuza [10]2 years ago

Answer:

Given,

Frame rate = 25 frames per second

To find,

Time interval between one frame and the next.

Solution,

We can simply solve this numerical problem by using the following process.

Now,

Number of frames = 25

Total time taken to display the given number of frames (ie. 25 frames) = 1 second

To calculate the time interval between one frame and next, we need to divide the time taken to display total number of frames by total number of frames.

So,

Time interval between one frame and next :

= Time taken to display total number of frames / Total frames

= 1/25

= 0.04 second

Hence, time interval between one frame and next is 0.04 second.

Three liters (3000 cm3) of oil is spilled onto a smooth lake. If the oil spreads out uniformly until it makes a circular oil sli
SVETLANKA909090 [29]

Answer:

4.38 km

Explanation:

Volume of oil slick, V = Area of oil slick, A × thickness of 1 molecule, d'

Since the oil slick spreads out in a circular area, it has the area of a circle.

So, V = πd²/4 × d'

d² = 4V/πd'

d = 2√(V/πd') where d = diameter of oil slick.

Since V = 3000 cm³ = 3000 × 10⁻⁶ m³ = 3 × 10⁻³ m³ and d' = 2 × 10⁻¹⁰ m

So, d = 2√(3 × 10⁻³ m³/(π × 2 × 10⁻¹⁰ m))

= 2√(3 × 10⁻³ m³/(6.283 × 10⁻¹⁰ m))

= 2√(0.477 × 10⁷ m²) = 2√(4.775 × 10⁶ m²)

=  2 × 2.19 × 10³ m

= 4.38 × 10³ m

= 4.38 km

A laborer pushes a box to distance of 20m. if the force required to push the box is 25N what will be the quantity of work done​
Marrrta [24]

Answer:

500 J

Explanation:

In the case of a rectilinear movement, the work is calculated as the product of Force (N) * movement (m). In your case, unless the angle between the force vector and the displacement vector is different from 0, the work is:

25 N * 20 m = 500 J

Two cars leave Calgary at the same time, travelling in opposite directions. Their average speeds differ by 5 km/h. After 2 h, th
dimulka [17.4K]
Let the first car's average speed be x

The second car's speed would be x+5

2(x+(x+5))=210

2x+5=105

2x=100

x=50

So the speed of the slower car is 50mph, and the speed of the faster car is 55mph
