Answer:
The force exerted by the child is 38.25 Newton
Explanation:
We use the formula F=mxa (m=mass and a= aceleration):
F= 45kg x 0,85 m/s2=38, 25 kgxm/s2= <em>38, 25 N</em>

Answer:
The percentage of mass recover from recrystallization = 24.69 %
Explanation:
Given that
Initial mass of crude acetanilide = 166 gm
The mass after recrystallization = 125 gm
The mass recover from recrystallization= 166 - 125 gm
The mass recover from recrystallization= 41 gm
The percentage of mass recover from recrystallization can be find as
The percentage of mass recover from recrystallization = 24.69 %
Answer:
Angle will be
Explanation:
We have given frequency of the sound f = 600 Hz
Vertical opening is of 0.8 meter
So width D = 0.8 m
Velocity of sound v = 340 m/sec
We know that wavelength
Now for the first minimum
