Answer:

F+20Hz

Explanation:

The resulting acceleration is 6.95 m/s².

Net force (F) = 153 N

Mass (m) = 22.0 kg

To find the resulting acceleration (a), we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. The equation can be written as:

F = m * a

Rearranging the equation, we have:

a = F / m

Substituting the given values, we get:

a = 153 N / 22.0 kg

Evaluating the expression, we find:

a ≈ 6.95 m/s²

Therefore, the resulting acceleration is approximately 6.95 m/s².

The answer is xcos x + sin x

Explanation:

d/dx (xsin x)

= x d/dx (sin x) + sin x d/dx (x)

= xcos x + sin x (1)

= xcos x + sin x

Thus, The answer is xcos x + sin x

Answer: 4.6 minutes

Explanation:

(254 mi/hr) x (1hr/60min)= 4.23 mi/min

(19.5mi) x (1min/4.23mi)= 4.6 minutes

When the fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr, then the dive lasted for 276.377 seconds

The total distance covered by any object per unit of time is known as speed. It depends only on the magnitude of the moving object. The unit of speed is meter/second. The generally considered unit for speed is a meter per second.

The mathematical expression for speed is given by

speed = total distance /Total time

As given in the problem The fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr

Total distance = 19.5 miles

Total time =?

average speed

By substituting respective values in the formula of speed

254 mi/hr = 19.5 miles/time

time = 19.5/254 hr

time = 0.0767716 hr

As we know 1 hr = 3600 seconds

0.0767716 hr = 0.0767716 ×3600 seconds

                       =276.377 seconds

Thus, the dive lasted for 276.377 seconds

Explanation:

Queremos crear un diagrama general para calcular el área de un triangulo.

Este será algo como:

Como naturalmente habra algunas variaciones segun el programa que utilicemos, lo voy a escribir de forma bastante general.

Primero definamos nuestras variables:

Por ejemple, en fortran usariamos algo como:

real:: B, H, A

Donde B será la variable que usaremos para la base, H para la altura, y A para el área.

Luego tenemos que escribir en pantalla algo que le diga al usario que debe introducir la base y el area.

Luego el programa debe ser capaz de leer ese input.

con algo de la forma:

B = read*input 1

H = read*input 2

Una vez tenemos definidas las variables, simplemente calculamos el área del triangulo:

A = H*B/2

Finalmente la podemos mostrar en pantalla con algo como:

print(A).

Lo que nos mostraría el valor del área.

Answer:

the magnetic field can be used to make electricity

Explanation:

Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy

Answer:

To calculate displacement, simply draw a vector from your starting point to your final position and solve for the length of this line. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. In physics, displacement is represented by Δs.

Answer:50m

Explanation:

Answer:

This is Newton's second law.

Newton's second law text:

(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)

F=ma

net force = mass x acceleration

I hope I helped you^_^

Answer:

Force is defined as the rate of change of momentum. For an unchanging mass, this is equivalent to mass x acceleration. So, 1 N = 1 kg m s-2, or 1 kg m/s2.

[A] Acidic in nature:-

[B] Basic in nature:-

Explanation:

a) The solutions can be classified as basic or acidic depending on their hydrogen ion concentration relative to pure water. If the value of pH is below seven, then the solution is acidic and if the pH is greater than seven then the solution is said to be basic.

b) Basic in nature means when a substance is soapy and bitter in taste and when a subtance changes red litmus blue. This nature of substance is basic.

Energy = (power) x (time)

Energy = (16 watt) x (5 hours)

Energy = 80 watt-hours

or

Energy = 0.08 Kilowatt-hours

or

1 watt = 1 joule/second

5 hours = 18,000 seconds

Energy = (16 joule/sec) x (18,000 sec)

Energy = 288,000 Joules

Explanation:

A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.

(16×5 ) watt-hour=80Wh.

Convert it to kilowatt-hour i.e 0.08 KWh/day.

So 0.08 KWh is the energy consumption for one day.
