Answer:
1101.96 J
Explanation:
Potential energy at top = mgh = 24*10*5 = 1200J
Kinetic energy at bottom = 1/2*m*v² = 0.5*24*(2.8)²= 94.08 J
Loss of energy = 1200 J - 98.04 J
= 1101.96 J
Thermal energy due to friction =1101.96 J
Answer:
178 cm3
Explanation:
From definition of density, it is mass per unit volume of an object, expressed as density=mass/volume and making volume the subject of the above formula we have volume= mass/density and substituting 0.00296 g for mass and 0.00001663 g/cm3 for density then we have
Volume=0.00296/0.00001663
Volume is approximately 178 cm3
Answer:
P is pressure ,rho(slanted p) is density,g is the acceleration due to gravity, v is velocity and h is height
Explanation:
Answer:
Explanation:
Given
Time taken to reach ground is 
Malda initial velocity 
Let h be the height of Cliff
using 
where, u=initial velocity
t=time
In first case chirpy drop downward thus u=0


For Milada there is horizontal velocity u=95 cm/s=0.95 m/s[/tex]
time taken to reach the ground will be same so distance traveled in this time with 0.95 m/s horizontal velocity is given by
