Answer:

0.05s

Explanation:

Given parameters:

Number of rotations  = 50times

Time taken  = 2.5s

Unknown:

Period  = ?

Solution:

The period is the time taken for a body to make one complete rotation. It is mathematically expressed as;

     Period  = \frac{time taken}{number of rotation}  

    Period = \frac{2.5}{50}    = 0.05s

It is easier to open the lid of a can using a spoon why?​
oksian1 [2.3K]

Answer:

It depends on how you use the spoon...

if you are keeping one end of the spoon and pressing other end, the force you provide is supported by the force due to gravity... Hence it is easy to open this way :)

F + G ... Where F is the force you provide and G is the force due to gravity.

If you connected 10 of these 12V (10 W) lamps in parallel, to the 12V source, how much current would the source have to supply
Flauer [41]

Answer:

T=8.33A

Explanation:

From the question we are told that:

Number of battery n=10

Voltage sourceE=12V

Lamp PowerP=10W

Generally the equation for Resistance is mathematically given by

 R=\frac{V^2}{P}

 R=\frac{12^2}{10}

 R=14.4ohms

Therefore

 R_{eq}=\frac{14.4}{10}

 R_{eq}=1.44

Generally the equation for Current is mathematically given by

 T=\ffrac{V}{Req}

 T=\frac{12}{1.44}

 T=8.33A
