(sorry I can only answer no. 1)
the climate is the weather over a long period of time (could be days, weeks, months, or years) while weather is only how the day has been on one day (e.g. sunny)

A pitcher throws a curveball that reaches the catcher in 0.64 s. The ball curves because it is spinning at an average angular ve
myrzilka [38]

Answer:

\Delta \theta=19.44\ rad

Explanation:

We just have to calculate what angular displacement a ball with an average angular velocity of 290 rev/min experiments in 0.64s. By definition, angular velocity \omega is the angular displacement \Delta \theta divided by the time elapsed:

\omega=\frac{\Delta \theta}{\Delta t}

Since 1\ rev=2\pi \ rad and 1\ min=60\ s, we can covert:

\omega=290\ rev/min=\frac{290\ rev}{min}(\frac{1\ min}{60s})(\frac{2\pi \ rad}{1\ rev})=30.37\ rad/s

Where the terms between parenthesis are equal to 1, so they just change the units. Then for our values we have:

\Delta \theta=\omega \Delta t=(30.37\ rad/s)(0.64s)=19.44\ rad

A toy airplane, flying in a horizontal, circular
Goshia [24]

Answer:

8.4 m/s

Explanation:

The toy completes 10 circle in 30 seconds. So its frequency of revolution is

f=\frac{10}{30 s}=0.33 Hz

The periof of revolution is the reciprocal of the frequency, so

T=\frac{1}{f}=\frac{1}{0.33 Hz}=3 s

The radius of the circular path is

r = 4.0 m

So the total distance covered by the toy in one circle is the length of the circumference:

2\pi r

And so the average speed is

v=\frac{2\pi r}{T}=\frac{2\pi (4.0 m)}{3 s}=8.4 m/s

DanielleElmas [232]
<span>Answer: So it gets to the top of the ramp and stops. The parallel force pushing it down the ramp is mg sin θ, but for it to move, the frictional force must be overcome. This frictional force is μmg cos θ, where μ is the coefficient of static friction. For movement, then, mg sin θ > μmg cos θ ==> tan θ > μ ==> θ > arctan 0.5 = 26.565° ==> θ = 27°</span>
