Answer:
The bowling ball would
Explanation:
Because it contains more weight! And that will make it fall down quicker.
Hope it helped
Answer:20000m/s
Explanation:
Frequency=10khz
Frequency=10x1000
Frequency=10000hz
Wavelength=2m
Speed= frequency x wavelength
Speed=10000 x 2
Speed=20000
speed=20000m/s
Answer:
fr = 65.46 N
, a = 8.74 m / s² and vf = 19.25 m / s
Explanation:
We write a reference system with an axis parallel to the slide and gold perpendicular axis, in this system we decompose the weight
sin 21.2 = Wx / W
cos21.2 = Wy / W
Wx = W sin21.2
Wy = W cos 21.2
We form Newton's equations
X axis
Wx -fr = m a
Y Axis
N- Wy = 0
N = Wy
fr = μ N
fr = μ (W cos 21.2)
fr = 0.113 63.4 9.8 cos 21.2
fr = 65.46 N
We replace and calculate the acceleration
W sin 21.2 - μ W cos 21.2 = m a
a = g (sin21.2 - μ cos 21.2)
a = 9.8 (without 21.2 - 0.113 cos 21.2)
a = 8.74 m / s²
This acceleration is along the slope of the slide, so we can calculate the distance
d = 21.2 m
vf² = v₀² + 2 a d
vf² = 0 + 2 a d
vf = √(2 8.74 21.2)
vf = √ (370,576)
vf = 19.25 m / s
3. Coal burning
The coal releases chemicals when it is burned. So it is chemical to thermal.
The specimen that will be on display is set up on stage. When working at greater magnifications when careful motions of the specimen slide are needed, a mechanical stage is employed.
<h3>What is a compound light microscope?</h3>
A microscope having several lenses and a separate light source is called a compound light microscope.
Ocular lenses are located in the binocular eyepieces of this type of microscope, while objective lenses are located in a rotating nosepiece that is located closer to the specimen.
Hence, the part of the compound light microscope is specimens placed for viewing is stage.
