Answer:
Archimedes' principle states that, when a body is partially or completely immersed in a fluid, it experiences an apparent loss in weight that is equal to the weight of the fluid displaced by the immersed part of the body.
Explanation:
Archimedes' principle allows the buoyancy of an object partially or fully immersed in a fluid to be calculated. The downward force on the object is simply its weight. Thus, the net force on the object is the difference between the magnitudes
of the buoyant force and its weight. If this net force is positive, the object rises; if negative, the object sinks; and if zero, the object is neutrally buoyant - that is, it remains in place without either rising or sinking. In simple words,
Answer:
The mass of the bat is 1.09 kg.
Explanation:
Given that,
The balance point of the glove, x = 74.9 cm
Mass of the glove, m = 0.56 kg
Center of mass of the baseball bat, C = 25.3 cm
Let M is the mass of the bat. The center of mass is given by the formula as :

X is 0 as it is at a end


M = 1.09 kg
So, the mass of the bat is 1.09 kg. Hence, this is the required solution.
Answer:
Part a)

Part b)

Explanation:
Part a)
as the mass of the suspension system is given as

also we have

so now for force balance we have



Part b)
Now we know that amplitude decreases by 63% in each cycle
so after one cycle the amplitude will become 37% of initial amplitude
so it is given as

also we know




here t = time period of one oscillation
so it is



now damping constant is


Answer:
t = 8.33 minutes
Explanation:
given,
Speed of Light, v = 3 x 10⁸ m/s
distance between sun to Earth = 1.5 x 10¹¹ m
time taken to reach earth = ?
we know,
Distance = speed x time


t = 500 s
1 min = 60 s
now, 
t = 8.33 minutes
time taken by the light to reach earth is equal to 8.33 minutes.
