Answer:
0.084 kg
Explanation:
I = 0.80 N-s (East wards) = 0.80 i N-s
u = 3.8 m/s = - 3.8 i m/s
v = 5.7 m/s = 5.7 i m/s
Let m be the mass of bat.
I = m (v - u)
0.8 i = m ( 5.7 i + 3.8 i)
0.8 i = m x 9.5 i
m = 0.084 kg
A boiling pot of water (the water travels in a current throughout the pot), a hot air balloon (hot air rises, making the balloon rise) , and cup of a steaming, hot liquid (hot air rises, creating steam) are all situations where convection occurs.

Answer:
its a conductor because it conducts electricity
Explanation:
Answer:
(a) 42°
Explanation:
According to the law of reflection:
Angle of incidence = Angle of reflection
So, angle of reflection = 62°
Angle of incidence = 62°
For refraction,
Using Snell's law as:
Where,
is the angle of incidence ( 62.0° )
is the angle of refraction ( ? )
is the refractive index of the refraction medium (water, n=1.33)
is the refractive index of the incidence medium (air, n=1)
Hence,
Angle of refraction =
= 42°
Answer:
the magnitude of the force that one particle exerts on the other is 79.08 N
Explanation:
given information:
q₁ = 3.77 μC = -3.77 x 10⁻⁶ C
q₂ = 4.39 μC = 4.39 x 10⁻⁶ C
r = 4.34 cm = 4.34 x 10⁻² m
What is the magnitude of the force that one particle exerts on the other?
lFl = kq₁q₂/r²
= (9 x 10⁹) (3.77 x 10⁻⁶) (4.39 x 10⁻⁶)/(4.34 x 10⁻²)²
= 79.08 N
