The answer is adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients.
Explanation:
Despite that adequate nutrition, regular physical activity, and practical ways to reduce calories while retaining important nutrients is one of the best strategy to reducing weight, most time it is very difficult for those that want to reduce or control their weight to discipline themselves enough to follow these routine. But one an individual that want to loose weight or live a healthy lifestyle is able to follow these procedures he/she will surely loose weight.
Answer:
A) vertically upward
Explanation:
Since the tyre is rotating with uniform angular speed and moving with constant linear speed
So as soon as a small stone is stuck into the groove of the tyre the speed of the stone is same as that of the tyre
so now we can say that stone will start revolving with the tyre of the car at constant angular speed and moving with uniform speed also
so here just after that the tangential acceleration of the stone must be zero while radial acceleration must be towards the center of the tyre given as
so we will have direction of net acceleration is towards its center so correct answer will be
A) vertically upward
Answer:
Explanation:
Given
Original Frequency 
apparent Frequency 
There is change in frequency whenever source move relative to the observer.
From Doppler effect we can write as
where
apparent frequency
v=velocity of sound in the given media
velocity of source
velocity of observer
here 
i.e.fork acquired a velocity of 
distance traveled by fork is given by
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
Answer:
Because the chemical energy is converted to electrical enegy in the cell phone
Explanation:
This set up is not a voilation of the first law of thermodynamics because the chemical energy is not lost, it is only being transformed into electrical energy.
According to the first law of thermodynamics "energy is neither created nor destroyed but transformed from one form to another".
- In a charged cell phone, the chemical energy is being transformed to electrical energy as you use it.
- A phone cannot directly be powered with chemical energy.
- The energy transformation to electrical energy makes it possible to use the phone.
- In this process no energy is lost nor created. But simply, energy is transformed.
