10 N 30 N 4kg net force = a=f/m=

Physics
1 answer:
ICE Princess25 [194]3 years ago
6 0

Answer:

a=5\ m/s^2

Explanation:

Two forces are 10 N and 30 N. Let us assume that two forces are acting in opposite directions. Net force will be :

F = 30 N - 10 N = 20 N

Now,

F = ma

⇒ a = F/m

So,

a=\dfrac{20}{4}\\\\a=5\ m/s^2

So, the acceleration of the object is 5\ m/s^2.

In a game of pool, why will the balls eventually stop after a collision?
Aneli [31]

As a ball rolls ... even if there were no air resistance ... the ball
has to push down and climb over every one of those little fibers
that stick up from the felt fabric on the table.  As it does that, each
little fiber brushes against the ball, and robs a tiny tiny bit of its
kinetic energy.

What is the magnitude of an electric field in which the electric force on a proton is equal in magnitude to its weight?Use 1.67×
vazorg [7]

The electric force on the proton is:

F = Eq

F = electric force, E = electric field strength, q = proton charge

The gravitational force on the proton is:

F = mg

F = gravitational force, m = proton mass, g = gravitational acceleration

Since the electric force and gravitational force balance each other out, set their magnitudes equal to each other:

Eq = mg

Given values:

q = 1.60×10⁻¹⁹C, m = 1.67×10⁻²⁷kg, g = 9.81m/s²

Plug in and solve for E:

E(1.60×10⁻¹⁹) = 1.67×10⁻²⁷(9.81)

E = 1.02×10⁻⁷N/C

Joe is an athlete and ran today. His exercise heart rate is 130. His THRZ is 147-179
Katyanochek1 [597]

Answer:

The correct option is;

a) Mike, he is within his target heart rate zone

Explanation:

The Target Heart Rate Zone (THRZ) is the range of the percentage of a person's maximal heart beat rate (MHR) targeted to be achieved during exercising. It is a very good way to gauge the comparative intensity of a person's exercise

Whereby, Joe's heart beat rate is below his THRZ and Mikes heart beat rate is within his THRZ, Mike is working harder.

Hence the correct option is (a) Mike, he is within his target heart rate zone.

PLZ HELP ME WITH THIS. In a dam, potential energy is stored in the _____. A.) generator B.) reservoir C.)turbine OR D.) flowing
vichka [17]
Flowing water. As a turbine is creating energy, as is a generator and a reservoir just holds still water. Flowing water can be pumped through a turbine or hydro scheme and be turned into energy. Another thing, as it says potential, it’s referring to something that could be/isn’t yet
