Answer: 50 m.

Explanation:

Assuming there is only 20N force acting on the object, use F = m * a where F is force, m is mass and a is acceleration.

You'll get a = 2.

Next, write what you know.

acceleration (a) = 2

initial velocity (u) = 5

final velocity (v) = 15

distance (s) = ?

Now, use v² = u² + 2as and find s.

The average height of an apple tree is 4.00 meters. How long would it take an apple falling from that height to reach the ground
kati45 [8]

Answer:

The time is 0.90 sec.

Explanation:

Given that,

Height = 4.00 m

We need to calculate the time

Using equation of motion

s = ut-\dfrac{1}{2}(-g)t^2

For free fall, u = 0

t =\sqrt{\dfrac{2s}{g}}

Where, s = distance

g = acceleration due to gravity

t = time

Put the value into the formula

t =\sqrt{\dfrac{2\times4.00}{9.8}}

t= 0.90\ sec

Hence, The time is 0.90 sec.

What is the voltage across each resistor?
kogti [31]

Answer:

see solution below

Explanation:

The given resistors are connected in series.

Equivalent resistance in series = 30 + 55 + 15

Equivalent resistance in series Rt = 100 ohms

Since the potential difference in the circuit = 36V

Get the current in the circuit first

I = V/Rt

I = 36/100

I = 0.36A

Get the voltage across 30ohms resistor;

V30 = 0.36 * 30

V30  = 10.8volts

Hence the voltage across the 30ohms resistor is 10.8volts

Get the voltage across 55ohms resistor;

V55 = 0.36 * 55

V55  = 19.8volts

Hence the voltage across the 55ohms resistor is 19.8volts

Get the voltage across 15ohms resistor;

V15 = 0.36 * 15

V15  = 5.4volts

Hence the voltage across the 15ohms resistor is 5.4volts
