A device employing a lens, shutter, and persistent light source that projects images from glass slides onto a flat white wall or cloth drape hung in the dark is image projection began with the MAGIC LANTERN
<h3><u>
Explanation:</u></h3>
The magic lantern works on the sliding runner technology. The image can be made larger in size and can be projected with the help of an optical device. When the technology of motion toy become older, this magic lantern is the modernized version of the motion toy technology. The modernization of the magic lantern was as an alternative of to motion-toy technology.
The photos and images that are taken can be increased in the size and projection can be made. These images can be enlarged in size by the help of a photographic images. this helps in image and also in taking photographs. This photographic image can be attached with Magic lantern. A long slide of glass helps in projecting the image on the walls or cloth drapes using magic lantern. This gives life to Shadows.
Answer:
thermal decomposition reaction
Explanation:
Answer:
c) 2 blocks
Explanation:
Her displacement is the difference between her starting point and her ending point.
Let's say she starts at the origin, (0, 0).
First, she goes 13 blocks east: (13, 0)
Next, she goes 4 blocks north: (13, 4)
Then she goes 8 blocks west: (5, 4)
Then she goes 6 blocks south: (5, -2)
Finally, she goes 5 blocks west: (0, -2)
The magnitude of her displacement is the distance between her initial and final positions: 2 blocks.
Answer:
1.9965 m/s²
Explanation:
Acceleration: This can be defined as the rate of change of velocity. The S.I unit of acceleration is m/s².
From the question,
F' = ma................ Equation 1
Where F' = horizontal force, m = mass of the box, a = acceleration of the box.
But,
F' = FcosФ................Equation 2
Where F = Force applied to the box, Ф = angle of between the force and the horizontal.
Substitute equation 2 into equation 1
FcosФ = ma
make a the subject of the equation
a = FcosФ/m.................... Equation 3
Given: F = 100 N. Ф = 37°, m = 40 kg.
Substitute into equation 3
a = 100(cos37°)/40
a = 100(0.7986)/40
a = 79.86/40
a = 1.9965 m/s²
