When a large block of ice is added to a hot cup of water then it won't melt the ice because mass of water is less. Therefore, heat released or given out by it will be less. Whereas lake is able to dissolve the large block of ice because lake has large mass and thus it will have more heat
Answer:
Explanation:
The displacement current is given by the expression;
where
All objects emit radiation as a result of their temperature. According to their temperature, electromagnetic radiation varies.
Answer:
We know that for a pendulum of length L, the period (time for a complete swing) is defined as:
T = 2*pi*√(L/g)
where:
pi = 3.14
L = length of the pendulum
g = gravitational acceleration = 9.8 m/s^2
Now, we can think on the swing as a pendulum, where the child is the mass of the pendulum.
Then the period is independent of:
The mass of the child
The initial angle
Where the restriction of not swing to high is because this model works for small angles, and when the swing is to high the problem becomes more complex.
Answer:
Computers make people's lives easier and more comfortable: they provide opportunities for staying in touch to billions of people who may very well be in different parts of the world. Today people can drive computerized cars and work for employers from other countries without even seeing them.
