Answer:

B) rain

Explanation:

The barometer is a device that is used to measure atmospheric pressure and, consequently, the height at which someone rises, as well as to approximately predict atmospheric changes. Thus, a rising barometer indicates an increase in air pressure, whereas a falling barometer indicates a decrease in air pressure.

In environments with low atmospheric pressure and, therefore, heat, the heated air tends to rise and, when reaching higher altitudes, condenses, forms clouds and precipitates. In this situation, the barometric pressure drops very, very quickly, indicating that a rain is coming.

A 500kg car is driven forward with a thrust force of 1500N. Air resistance and friction acts against the motion of the car with
Wittaler [7]
2m/s^2, this is because F=ma, meaning a is also equal to F/m. The car applies 1500N in one direction and outside sources apply a total of -500N, meaning the 500kg car is moving forward with a total of 1000N of force. Taking the total 1000N and dividing it by 500kg gives you and acceleration of 2m/s^2. Hope this helps!

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 60.0 m/s , and it leav
nata0808 [166]

Answer:

F = -307.4 N

Explanation:

It is given that,

Mass of the baseball, m = 0.145 kg

Initial speed of the baseball, u = 60 m/s

Final speed of the baseball, v=65\ cos(30)=56.29\ m/s

Time of contact, t=1.75\ ms=1.75\times 10^{-3}\ s

(a) It is assumed to find the horizontal component of average force. It is given by :

F=m\dfrac{v-u}{t}

F=0.145\dfrac{56.29-60}{1.75\times 10^{-3}}

F = -307.4 N

So, the horizontal component of average force is 307.4 N. Hence, this is the required solution.
