Answer:
Wavelength = 0.68 meters.
Explanation:
Wavelength gives the distance between a point of rarefaction and the next compression point, in the resulting sound.
Given the following data;
Frequency = 500 Hz
Speed of sound = 340 m/s
To find the wavelength;
Wavelength = speed/frequency
Wavelength = 340/500
Wavelength = 0.68 meters
Answer:
the cognitive abilities of an individual to learn from experience to reason well, and to cope effectively with the demands of daily living
Explanation:
Yes that can be understood by a simple example
Suppose two people are in exam
- A difficult and logical question came
- The person can use his cognitive abilities faster can solve that
As we know that work done by external environment is given as
here we know that
P = 200 N/m^2
now we will have
so work done by external atmosphere will be 40 J
so correct answer will be
A. 40 joules
Answer:
432 J
Explanation:
When moving linearly:
Kinetic Energy = (1/2)mV^2
So here you have:
KE=(1/2)(6)(12^2)=(1/2)(6)(144)=432
The unit for energy is Joules (J), so your answer would be 432 J.
Answer:
a) Explanation below. b) Explanation below
Explanation:
Torque is defined as the product of a force by a radius, while momentum is defined as the product of force by a distance. Mathematically we would have
T = F * r
M = F * d
where:
T = torque = [N*m]
M = moment = [N*m]
F = force =[N]
d = distance [m]
r = radius [m]
Although they have the same units, the difference between them is the application. For the case of torque this is always applied in parts that are in rotation, such as the shafts of cars, the shafts of pumps, torque in gears and etc. While the moment can be applied to a body without the need for it to rotate.
A couple, is as its name suggests a couple of forces of equal magnitude but opposite sense and do not share a line of action. A body under the action of a couple of forces tends to rotate the body without moving it from one point to another.
