Answer:
1.001 m
Explanation:
We have to find the least measurement of the instrument.
In this case the least measurement = 1 mm
= (1/1000) m
= 0.001 m
The measurement that is precise from this instrument should be to the nearest thousandth when taken in meters.
Therefore the answer is: 1.001 m

Explanation:
When the two samples of water (hot water and cold water) are put in contact, thermal energy is transferred from the hot water to the cold water. This occurs because heat always flows from a hotter object to a colder object. The heat is transferred by collision between the molecules: the molecules of the hot water have on average more kinetic energy than the molecules of cold water, so when they collide to each other, the molecules of hot water transfer energy to the molecules of cold water. As a result, the kinetic energy of the molecules of cold water increases, and therefore the temperature of the cold water increases, while the temperature of the hot water decreases. This process lasts until the molecules of the two samples have same average kinetic energy: when this occurs, the two samples have.
W=Fd. Force is not given so we solve for it. F=ma, m=5kg, a=2m/s^2, F=10N. Distance is not given so we solve for it, x=.5a(t^2)=.5(2)(7x7)=49m. F=10N, d=49m, W=490J.
Answer:
graph 1
Explanation:
When it comes to a graph showing "constant acceleration," the line should be straight and upward <em>(positive acceleration) or </em>straight and downward <em>(negative acceleration).</em> The variables for acceleration are time and velocity. The independent variable (time) should be placed on the<em> x-axis</em> while the dependent variable (velocity) should be placed on the<em> y-axis.</em> As time increases, the velocity increases the same way. It doesn't slow down or changes. This makes it constant. <u>They are also directly proportional to each other</u>. This is evident on the first graph.
Answer:
Explanation:
The artificial gravity generated by the rotating space station is the same centripetal acceleration due to the rotational motion of the station, which is given by:
Here, r is the radius and v is the tangential speed, which is given by:
Here is the angular velocity, we replace (2) in (1):
Recall that .
Solving for :
