Answer:
It is virtual and behind the mirror
Explanation:
When an image is produced by a mirror, we have the following situations:
- The image is said to be in front of the mirror if it is on the same side of the object, with respect to the mirror
- The image is said to be behind of the mirror if it is on the opposite side of the object, with respect to the mirror
Moreover:
- The image is said to be real if it is in front of the mirror
- The image is said to be virtual if it is behind the mirror
In this case, the image (located at point I) is on the opposite side of the object (located at point O), so it is virtual and behind the mirror.
Answer:
Advantages: Very sturdy, can have several cracks in structure before breaking
disadvantages: best for short distances, not attractive, hard to maintain
Answer:
The value of the inductance is 175.9 mH.
Explanation:
Given that,
Capacitor 
Frequency = 60.0 Hz
The inductor and capacitor is connected in parallel, the voltage across each of these elements is the same.
We have,

Using ohm's law




Put the value into the formula




Hence, The value of the inductance is 175.9 mH.
Answer:
Amplitude
Explanation:
A wave is a periodic oscillation that carries energy, but not matter, through space or through a medium.
A wave is characterized by the fact that the particles in the medium oscillate around a fixed point, but there is no overall movement of particles in the direction of the wave (this means, only energy is transferred, while matter is not transferred).
A wave is also characterized by several properties, namely:
Amplitude: it is the maximum distance the particles of the medium move from their resting positions
Frequency: the number of oscillations of a certain particle per second
Wavelenght: the distance between two points of the wave that have same shape
Period: the time it takes for one particle of the wave to complete one oscillation
So, the answer is
Amplitude
Answer: 0m/s²
Explanation:
Since the forces acting along the plane are frictional force(Ff) and moving force(Fm), we will take the sum of the forces along the plane
According newton's law of motion
Summation of forces along the plane = mass × acceleration
Frictional force is always acting upwards the plane since the body will always tends to slide downwards on an inclined plane and the moving acts down the plane
Ff = nR where
n is coefficient of friction = tan(theta)
R is normal reaction = Wcos(theta)
Fm = Wsin(theta)
Substituting in the formula of newton's first law we have;
Fm-Ff = ma
Wsin(theta) - nR = ma
Wsin(theta) - n(Wcos(theta)) = ma... 1
Given
W = 562N, theta = 30°, n = tan30°, m = 56.2kg
Substituting in eqn 1,
562sin30° - tan30°(562cos30°) = 56.2a
281 - 281 = 56.2a
0 = 56.2a
a = 0m/s²
This shows that the trunk is not accelerating
