As a crate is resting on the inclined surface of the ramp we have following forces on the crate
1. Weight of the crate vertically downwards
2. Normal force due to ramp perpendicular to the surface
3. static friction force along the ramp upwards
so here we know that crate is at rest
so we can say that
normal force is balanced by component of weight of crate
so we have
also we can say that friction force is balanced by another component of weight of the crate
so friction force is less than the weight of the crate and it will act opposite to it
Question 2 is because the passengers have inertia, which is a tendency to resist change in motion
Each Celsius degree is the size of 1.8 Fahrenheit degrees. So you need dip your Fahrenheit thermometer into the sample, see where you're starting, and then warm it up to a temperature that reads (37.1 x 1.8) = 66.8 Fahreheit degrees higher.
Answer:
Number of times a cricket chirps.
Explanation:
Let us use a graph to understand the function Here the entomologist wants to know the effect of temperature on the number of chirps of a cricket so, the chirps should vary with temperature. The opposite cannot be true i.e., the temperature is not dependent on the number of chirps rather the number of chirps are dependent on temperature.
So, the x axis will be represent the temperature and the y axis will represent the number of chirps.
Hence, the dependent variable will be number of times a cricket chirps i.e., the y axis.
Chiefly in science fiction) an invisible barrier of exerted strength or impetus.
