Answer:
P = F/A = 600.0 / (2.0(0.40)) = 750 N/m² = 750 Pa
Explanation:
Answer:
a. 0.8 mW/m² b. 1.6 mW/m² c. 6.4 mW/m²
Explanation:
Intensity,I = P/A were P = power and A = area = 4πr² were r = distance from electric guitar = 5.0 m.
a. When P = 0.25 W, I = 0.25 W/4π5² = 0.25 W/100π = 0.00079 W/m² ≅ 0.0008 W/m² = 0.8 mW/m²
b. When P = 0.50 W, I = 0.50 W/4π5² = 0.50 W/100π = 0.00156 W/m² ≅ 0.0016 W/m² = 1.6 mW/m²
c. When P = 2.0 W, I = 2.0 W/4π5² = 2.0 W/100π = 0.00636 W/m² ≅ 0.0064 W/m² = 6.4 mW/m²
Answer:
The correct answer is - true.
Explanation:
Changes in the higher authorities or managers or coworkers can be a warning sign before a layoff, however, a company or organization needs to give an official notice before a particular time period before the layoff.
The layoff is a temporary suspension or permanent termination from the employment of an employee due to reasons related to business such as reducing manpower or staff and less work in the organization. These reasons can lead to a change in the behavior of the managers, coworkers, and subordinates.
A sphere is charged with electrons to −9 × 10−6 C. The value given is the total charge of all the electrons present in the sphere. To calculate the number of electrons in the sphere, we divide the the total charge with the charge of one electron.
N = 9 × 10−6 C / 1.6 × 10−19 C
N = 5.6 x 10^13
A magnet sitting next to a wire does not induce a current in the wire because <span> the magnet is very small and short compared to the coil radius. If you pretend it's two individual monopoles, they're only a few mm apart, so at several cm there's almost perfect cancellation of the fields.</span>
