A horse is pulling 53.0 kg plow forward while the ground exerts a 275 N force, and the plow accelerates at 0.222 m/s^2. what is
JulsSmile [24]
Answer:
Magnitude of force the ground exerts on the plow = 263.234 N

Explanation:
Magnitude of force the ground exerts on the plow = Fground - Fplow
We are given that:
Fgound = 275 N
We will now calculate Fplow as follows:
Fplow = mass of horse * acceleration of plow
Fplow = 53 * 0.222
Fplow = 11.766 N

Now, substitute in the above equation to get magnitude of force the ground exerts on the plow as follows:
Magnitude of force the ground exerts on the plow = Fground - Fplow
Magnitude of force the ground exerts on the plow = 275 - 11.766
Magnitude of force the ground exerts on the plow = 263.234 N

Hope this helps :)

At what distance r from a point charge is the electric potential due to that point charge 0 v?
galben [10]

Answer:

Infinite Distance

Explanation:

The electric potential due to a point charge can be expressed by the following equation:

V=\frac{kQ}{r}

Here,

V is the electric potential due to the point charge

k is the proportionality constant

Q is the magnitude of the point charge

r is the distance from the charge

As the value of r increases, the value of V decreases since there is an inverse relation between the two. The value of V can be absolutely 0 when the distance from the charge is infinite i.e. r is infinite. Mathematically, dividing a number by infinity results in zero. Also theoretically speaking, at infinite distance the electric field lines won't approach and hence the electric potential would be zero.

How strong does an earthquake have to be to cause a tsunami
Vesnalui [34]

Answer:

An earthquake with the magnitude of more than 7.5 on the Richter scale can cause to a destructive Tsunami.

Explanation:

  • According to International Tsunami Information center, the cause of the most destructive tsunami is shallow and large earthquake with the epicenter or fault line on the ocean floor or near the ocean floor.
  • When the tectonic plates (are pieces of earth's crust and uppermost mantle) are collided with each other then the earthquake occurs. This results in the displacement of large area of ocean floor from few km to 1000 km or more. This displacement of ocean floor in the formation of tsunami waves.
  • Like in the 1960, the tsunami in Chile was resulted due to earthquake with the magnitude of 9.5 on Richter scale with rupture area of over 1000 km. This tsunami not only cause destruction in Chile but also affected the other countries like Japan.
