Answer:

F = m×a  

60 N = 30 kg × a  

30 × a = 60  

a =  60/30  

a =  2 m/s²

 

The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

Explanation:

If the net force increases while the mass of the object remains the same, the amount of acceleration also increases.  

However, when the mass of the object increases while the net force remains the same, the amount of acceleration decreases.  

Brainliest plz? thx

Pls someone I need it urgently and explain Solving and explanation so I can understand Thank you
Temka [501]

Answer:

   f = 6.37 Hz,       T = 0.157 s

Explanation:

The expression you have is

       y = 5 sin (3x - 40t)

this is the equation of a traveling wave, the general form of the expression is

      y = A sin (kx - wt)

where A is the amplitude of the motion, k the wave vector and w the angular velocity

Angle velocity and frequency are related

         w = 2π f

         f = w / 2π

from the equation w = 40 rad / s

        f = 40 / 2π

        f = 6.37 Hz

frequency and period are related

       f = 1 / T

       T = 1 / f

       T = 1 / 6.37

       T = 0.157 s

49. In what direction does the force of friction act?
DedPeter [7]
I believe it always acts in the direction opposite to that of the object in motion, so if the force was applied to the left then friction acts in the right

hope that helps

The electric field inside a cell membrane is 8.0 MN/C. Part A What's the force on a singly charged ion in this field?
dlinn [17]

Answer:

Force on the singly charged ion will be 12.6\times 10^{-13}N

Explanation:

We have given electric field E = 8 MN/C

So electric field in N/C will be E=8MN/C=8\times 10^6N/C

It is given that ion so charge on ion will be equal to e=1.6\times 10^{-19}C

We have to find the electric force on the ion

Electric force is equal to F=qE, here q is charge and E is electric field

So force on the charge will be equal to F=8\times 10^6\times 1.6\times 10^{-19}=12.6\times 10^{-13}N

So force on the singly charged ion will be 12.6\times 10^{-13}N
