Hoochie [10]3 years ago

Answer:

Explanation:

g = GM/R²

as gravity decreases by the inverse of the square of the distance, increasing the distance by 4 times will reduce gravity to 1/16 that at the surface

9.8 / 16 = 0.61 m/s²

If a ball is dropped and takes 6.5 seconds to hit the ground below. How far did it fall? Remember in free fall g= -9.8 m/s/s. Wh
vovikov84 [41]

Answer:

See the answers below.

Explanation:

To solve this problem we must use the following equation of kinematics.

y=y_{o}+v_{o}*t+\frac{1}{2}*g*t^{2}  \\

where:

y - yo = Fall distance [m]

Vo = initial velocity = 0 (dropped)

t = time = 6.5 [s]

g = gravity acceleration = 9.8 [m/s²]

Now replacing:

y-y_{o}=0 +\frac{1}{2} *9.8*6.5^{2}\\y-y_{o}=207 [m]

The question is related to the distance between the points where the ball was dropped and the ground.

The variables used are gravitational acceleration, time, fall distance, initial velocity.

mojhsa [17]

Answer:

The magnitude of the electric field between the membranes is  1.13 x 10⁶ N/C

Explanation:

Given;

the distance of separation of the parallel plate capacitor, d =  10nm

the charge density, σ = 10⁻⁵C/m²

the magnitude of the electric field between the membranes, is calculated using the formula below;

E = σ / ε₀

Where;

ε₀ is permittivity of free space, = 8.85 x 10⁻¹² C²/Nm²

E is magnitude of the electric field between the membranes

σ is surface charge density

E = (10⁻⁵) / (8.85 x 10⁻¹²)

E = 1.13 x 10⁶ N/C

Therefore, the magnitude of the electric field between the membranes is  1.13 x 10⁶ N/C
