The answer is 266. Hope that helps!
Answer:
P = 1.45 hp or 1.94kW
Explanation:
Given:
v = 2.5m/s
uk = 0.06
m = 60kg
Fk = uk*m*g*fsin(15)
Fk = 0.06*85*9.81*60*sin(15)
Fk = 776.15 N
Power=force*speed
P = F*v
P = 776.15N*2.5m/s
P = 1940.36 W
1 Horsepower = 0.7457 Kilowatts
P = 1.45 hp
If you're careful, you ought to be able to observe ANY of these properties
without any effect on the substance:
Absorption, albedo, angular momentum, area, color, concentration,
density, elasticity, electric charge, electrical conductivity, flow rate,
electrical impedance, electric potential, fluidity, length, location, mass,
luminance, luminescence, luster, magnetic field, momentum, opacity,
permeability, permittivity, plasticity, pressure, radiance, solubility, spin,
specific heat, resistivity, reflectivity, refractive index, temperature,
thermal conductivity, velocity, viscosity, or volume.
Graduate from college ! I’m a freshman at SDSU :) two things would be to stay dedicated to my studies and not give into distractions!!!
The wave characteristic that is the same for both waves is wavelength.
- Two waves with the same frequency will also have the same wavelength, amplitude, speed, and period. When two waves are travelling at the same frequency, it denotes that their duration and amplitude are also the same.
- When two waves of the same frequency and amplitude interfere constructively, their peaks and troughs align as shown in diagram A above. As a result, the original waves' amplitude is doubled, resulting in a sound wave that is twice as loud.
Thus, Equal frequencies are shared by two waves moving through the same region in the same direction.
