Answer:
v = 0.4712 m / s In the opposite direction of the turntable
Explanation:
For this exercise the mouse to remain motionless must run at the same speed as the record player point moves,
Let's use rotational kinematics to find the speed of the record player at the point where the mouse is
v = w r
Let's reduce the magnitude to the SI system
w = 45 rpm (2π rad / 1rev) (1 min / 60s) = 4.712 rad / s
r = 10 cm = 0.10 m
Let's calculate
v = 4.712 0.10
v = 0.4712 m / s
In the opposite direction of the turntable
Independent variable - Water depth
The independent variable is something that is purposely changed in order to see the effects of change on the dependent variable. So since Carl wants to measure the temperature of water at different depths we will purposely change the depth of the water in order to observe how this would affect the temperature.
Dependent variable - Temperature of the water
The dependent variable is something that is dependent on the independent variable and is assumed to change as the independent variable changes. So we can determine that the temperature of the water is the independent variable as Carl expects it to change with the depth of the water. Another reason we can determine this is the dependent variable is because Carl can change the depth of the water measured but not the temperature of the water depths.
Answer: Reflection by clouds
Explanation:
Only some shortwave radiation from the sun reaches the Earth's surface because solar radiation is being reflected by thick clouds and thin clouds transmit the solar radiation.
About 31 % of solar radiation is reflected by clouds. The tiny water particle scatters 20-90 % of incoming sunlight giving them a bright white appearance.
The force that acts on all objects, all the time on Earth is gravitational force.
The force that surface exert on an object perpendicularly is normal reaction.
<h3>What force acts on all objects, all the time on Earth?</h3>
- Force due to gravity is gravitational pull on objects due to its position on earth's surface.
The force due to gravity on object's is calculated by applying Newton's second law of motion as follows;
F = mg
where;
- m is the mass of the object
- g is acceleration due to gravity
The force that surface exert on an object perpendicularly is normal reaction.
Thus, the force that acts on all objects, all the time on Earth is gravitational force.
