Answer: 25Hz
Explanation:
Given that:
Wavelength (λ) = 0.4m (the distance between the peaks of a wave is known as wavelength)
Frequency F = ?
Speed of wave V = 10 m/s
The wave frequency is the number of cycles which the wave complete in one second. It is measured in hertz, and represented by the symbol F
So, apply the formula V = F λ
10m/s = F x 0.4m
F = 10m/s / 0.4m
F = 25Hz
Thus, the frequency of the wave is 25 Hertz.
Answer:
Length of pipe organ(L) = 0647 m (Approx)
Explanation:
Given:
Temperature (T) = 14°C
Fundamental frequency (F) = 262 Hz
Speed of sound (v) = 331 + 0.60(T) m/s
Find:
Length of pipe organ(L)
Computation:
Speed of sound (v) = 331 + 0.60(14) m/s
Speed of sound (v) = 339.4
Length of pipe organ(L) = Speed of sound (v) / 2(Fundamental frequency)
Length of pipe organ(L) = 339.4 / 2 (262)
Length of pipe organ(L) = 0647 m (Approx)
Answer:
The force is 86.5×10^9 N towards the negative charge (to the right)
Explanation:
The electrostatic force on the charges is given by Coulomb's law;
F= Kq1q2/r^2
This an inverse square law.
F= electrostatic force on the charges
K= constant of Coulomb's law
q1 and q2= magnitude of the charges
Since K= 9.0×10^9Nm^2C^2
F= 9.0×10^9 × 5 × 3/(1.25)^2 = 135×10^9/1.56
F= 86.5×10^9 N
The force is 86.5×10^9 N towards the negative charge.
<span>If we have less power, then we could have less work done
in the same amount of time, or we could have the same
amount of work being done over a longer period of time.
In either case, the quotient of
work / time
would be a smaller number.

The sailboat will be the give-way vessel or it will have the right of way always unless they are using the motor power of the sail or if the other boat cannot travel, then the sailboat would have to give way. Also, a sailboat will give the right of way to large ships that cannot maneuver. When a sailboat is in motor power, it will be measured as a power boat.
. what this says is that in order to figure out Fg(Force of gravity), we must take into account G( gravitational constant 6.67x10^-11) x M1(mass 1) x M2(mass2) / d^2(ditance squared). Mass is measured in Kg(kilograms). G never changes,and Fg is in Newtons. In terms of planets, you must take into account the radius of the planet within your distance. In Layman terms, You use all three to figure out how much gravity one object exerts on another and vice versa.
