To solve this problem we will use the vector concept given by the cross product between two perpendicular vectors and which results in a vector perpendicular to these two. From the definition of the Magnetic Force we have to
From the property of cross product the magnetic force should point in the direction perpendicular to the plane containing the vectors v and B.
The direction of velocity is north, and the direction of the magnetic force is northeast.
This cannot be the case, as the direction of magnetic force is not perpendicular to the direction of velocity of the charge.
Therefore the correct option for the direction of the magnetic field is <em>"This situation cannot exist because of the relative orientations of the velocity and force vectors" </em>
Aluminium, or heavier version copper.
Answer:
Explanation:
Given
Bianca is at 
i.e. distance between origin and Bianca is 
time taken to reach Bianca eyes is
i.e. Cracker exploded at 
because it is observed at 
Time taken by second cracker flash to reach Bianca eyes
Therefore it will be observed at 
Answer:
Elastic potential energy into kinetic energy
Explanation:
Initially the energy is stored inside the spring, which is compressed. This form of energy is called elastic potential energy, and its formula is
where k is the spring constant, which gives the 'strength' of the spring, while x is the compression/stretching of the spring with respect to its equilibrium position.
When the spring unwinds, it returns to its equilibrium position, so x becomes zero and the potential energy converts into another form of energy, which is related to the motion of the car (in fact, the car starts moving). This form of energy is called kinetic energy, and its formula is
where m is the mass of the car and v is its speed.
First, you have to write what you know:
V = 3.60 m/s
D = ?
T = 18.4 s
Next, you plug everything into this formula:
V = D/T
3.60 m/s = ?/18.4 s
Then, you multiply 3.60 m/s and 18.4 s
D = 66.24 m
