The objects that look black are all tied for first place.
Wavelength is the length from one peak of a wave to the next, while frequency is the amount of waves present in a unit of time. The greater the wavelength the smaller the frequency. The smaller the wavelength, the bigger the frequency.
To calculate the number of electrons from spherical conductor first we use the formula,
Here, k is a constant with a value of , q is the charge and r is the radius and its value of 0.200 m.
Substituting these value in above formula, we get
or
Now number of electron,
Hence, the number of electrons to be removed from conductor would be
The answer is true it is because when yielding, it is advisable that the driver of the vehicle to slow down, when it is safe to pass through, oncoming intersection, and to be aware of vehicles that are oncoming. It allows vehicles to move ahead by giving them the right of way for yielding enables the driver to slow down and give them the way especially with oncoming vehicles.
Answer:
1) John's ball lands last.
2) All three have the same total energy
Explanation:
John's ball will land last because his ball was projected at the largest angle. This means that the ball will spend more time in the air when compared to the other balls.
The total energy in a projected particle is the sum of its kinetic energy (0.5mv^2) and its potential energy due to its height (mgh). The total kinetic energy can be as a result of both, or at times fully transformed to either of the energy. For example, at the maximum height, the kinetic energy of John's ball is zero and is fully transformed into potential energy due to that height, whereas George's ball will mostly posses kinetic energy and a little potential energy. The three ball are assumed to have the same properties and are projected with the same initial velocity. This means that they all have the same kinetic energy at the instance of projection which can then be transformed into potential energy, or maintained as a combination of both throughout the flight or simply transformed into potential energy, but the total energy is always conserved.
