A tennis ball is dropped from 1.43 m above the

Physics
1 answer:
Rudiy274 years ago
4 0

Answer:

-5.29 m/s

Explanation:

Given:

y₀ = 1.43 m

y = 0 m

v₀ = 0 m/s

a = -9.8 m/s²

Find: v

v² = v₀² + 2a (y − y₀)

v² = (0 m/s)² + 2(-9.8 m/s²) (0 m − 1.43 m)

v = -5.29 m/s

14) Modify the method that calculates the sum of the integers between 1 and N. Have the new version match the following recursiv
Setler [38]

Explanation:

Let solve the program using Java programming language

Method: method means group of statements to perform some operation.

             let call the method sum.

Parameters: list of variables that are use in the method for declaration.

<u>The code</u>

public int sum (int number)

int answer;

if (number == 1)

answer = number;

else

{

int half = number/2;

int span = number - half;

answer = sum(half) + sum(span) + (half * span);

}

answer result;

}

Firstly we defined the method called sum(), the method takes only one parameter which is number and return the answer(sum of  the integers 1 and N).

if the number is equal to 1, so it will return the number and if the number is not equal to 1 it will divide the number by 2 and get the span(span used to shift upper range).And result will add sum of half, sum of span and product of half span.

What is the orbital period in years of a planet with a semi major axis of 35 au
mezya [45]

Answer:

Orbital period of the planet will be 207.06 year                      

Explanation:

We have given the planet have the semi major axis as 35 au

We have to find the orbital period of the planet

From Keplar's third  law there is relation between the orbital period and semi major axis which is t T^2=R^3

So T^2=35^3

T^2=42875

T=207.06year

So orbital period of the planet will be 207.06 year

An RLC series circuit consists of a 50 Ω resistor, a 200 μF capacitor, and a 120-mH inductor whose coil has a resistance of 20 Ω
solmaris [256]

Answer:

182.9 Volts

Explanation:

R = resistance of the resistor = 50 Ω

C = capacitance of the capacitor = 200 μF = 200 x 10⁻⁶ F

L = Inductance of the inductor = 120 mH = 0.12 H

f = frequency = 60 Hz

Capacitive reactance is given as

X = (2πfC)⁻¹

X = (2(3.14) (60) (200 x 10⁻⁶))⁻¹

X = 13.3 Ω

Inductive reactance is given as

X' = 2πfL

X' = 2(3.14) (60) (0.12)

X' = 45.2 Ω

Impedance of the circuit is given as

z = √(R² + (X' - X)²)

z = √(50² + (45.2 - 13.3)²)

z = 59.31 Ω

V = rms emf of the source = 240 Volts

rms voltage across the inductor is given as

V' = V z⁻¹ X'

V' = (240) (59.31)⁻¹ (45.2)

V' = 182.9 Volts
