Answer: is it .03oz ?
Explanation: I really aren’t sure
I have no idea how too do that work sheet but try looking for the answer key online by searching for the name of the worksheet
Answer:
n = 1.49
Explanation:
Given that,
Angle of incidence = 30 degrees
Angle of refraction = 19.5 degrees
We need to find the refractive index of the honey. Using Snell's law, we can find it as follows :
So, the refractive index of honey is 1.49.
Answer:
If a body is moving with uniform velocity, acceleration is zero. So net force acting on it will be also zero. But the body has energy due to its constant motion.
Answer:
156.24N
Explanation:
From the data above;
Mass = 23g = 0.023kg
V = 88m/s
Kinetic energy = ½mv²
K.e = ½* 0.023 * 88²
K.E = 89.056J
The force required to accelerate the arrow to that speed and energy in 0.57m
Using equation of motion;
V² = U² + 2as
But U =0
V² = 2as
a = v²/2s
a = 88² / (2*0.57)
a = 6792.98m/s²
The force (F) that accelerates the arrow with that velocity = ?
F = M*a
F = 0.023 * 6792.98
F = 156.24N
