Answer:
171 ft
Explanation:
The distance to be calculated is AB
AB = AC + BC
AC; Cos 60 = AC ÷ 135
AC = 135 cos 60 = 67.5 ft
BC; Cos 40 = BC ÷ 135
BC = 135 cos 40 = 103.416 ft
AB = 67.5 + 103.416 = 170.9159998210 ft
Distance between starting point to end point = 171 ft
Answer:
Explanation:
- The volume of water displaced by immersing the object is equal the amount of water spilled and caught by Dr. Hewitt.
- The amount of water is proportional to the volume of object of fraction of object immersed in water will lead to the same fraction of water displaced and caught by Dr. Hewitt.
- When the object is immersed the force of Buoyancy acts against the weight and reducing the scale weight.
- The amount of Buoyancy Force is proportional to the fraction of Volume of object immersed in water; hence, the same amount is spilled/lost.
A light-year is a unit of distance.
The definition of a light-year is the distance light travels in one year.
Answer:
1.07 nT
Explanation:
We know that E/B = c where E = electric field amplitude = 320 mV/m = 0.32 V/m, B = magnetic field amplitude and c = speed of light = 3 × 10⁸ m/s.
So, B = E/c
Substituting E and c into B, we have
B = E/c
= 0.32 V/m ÷ 3 × 10⁸ m/s
= 0.1067 × 10⁻⁸ T
= 1.067 × 10⁻⁹ T
= 1.067 nT
≅ 1.07 nT
