Answer:
8962.5 N
Explanation:
From fundamental kinematics equations, acceleration, a is given by 
where v is final velocity, u is initial velocity and t is time
We also know that force is a product of mass and acceleration of an object and substituting in the formula F=ma we obtain
where m is the mass of the body
Therefore, the force is 8962.5 N
Answer:
Slit separation, 
Explanation:
It is given that,
Wavelength of light, 
The angle between the central bright fringe and the second dark fringe, 
In case of double slits, the condition for dark fringe is given by :
n = 2
So, the slit separation is 
. Hence, this is the required solution.
Answer:
Static stretching.
Explanation:
It is static stretching because it is a form of stretching which u can do actively for a period of time and you hold position for about 30 to 60 seconds which allow the muscles and connective tissues to lengthen. It is done after work out with out movement in order to loosen up muscles so as to gain flexibility.
Answer:
13.33 seconds
Explanation:
At maximum height, the equation of motion becomes:
<em> v = u + at</em>
Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:
<em>v = at</em>
<em>v = 480 k</em>m/hr = 133.333 m/s
10t = 133.333
t = 133.333/10
t = 13.33 seconds.
<em>The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is </em><em>13.33 seconds</em><em>.</em>
The sound waves travel through the sea which creates movement which can be felt all the way in Italy in the sea- like a domino effect
