Given:
B(Magnetic field): 1.5 T
q= 7.5 microcoulombs
v= 1.75 x 10 ∧6 m/s
The angle ∅ between B and v is 45 °.
Now we know that F= qvB sin ∅
Substituting these values we get:
F= 7.5 x 10∧-6 x 1.75 x 10∧6 x 1.5 x sin 45
F= 16.752 N
Answer:
Okay
Explanation:
First we should quickly remind ourselves of the equation for density:density= mass/ volumeTo calculate the density we need a method of measuring the mass of each object and another method for measuring the volume of each object. To measure the mass in both cases we can simply use a measuring balance. To measure the volume we will need to use 2 separate methods. For the cube we can simply measure the length, height and depth with a ruler, multiply our measurements and we obtain the volume. The statue is a little more tricky because it has an irregular shape so we can't use the ruler anymore. Instead we should use graduated tank/trough of water. First of all measure the amount of water in the tank before putting in the statue. Then submerge the statue in the water and take another measurement of the volume of water in the tank. The statue will displace the water in the tank giving a higher value. We finally subtract the initial volume from the final volume and we should obtain the volume of the statue.We now have all the measurements necessary to calculate the density of both objects!
