Which expression correctly describes force using SI units
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.
Kilogram-force: kgf
A net force of 153 N accelerates a 22.0 kg mass. What is the resulting acceleration?
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.

Answer:
a) the most dangerous combination of tires and roads surfaces are old tires on wet concrete because it shows the longest distance moved by a car when the brake is pushed
b) Old tires on wet concrete
c) wet tires require longer braking distance than dry tires because the wet surface on the tires slide rather
than stopping gradually.
The fastest and longest skydive fell an amazing 19.5 miles. His average speed while falling was 254 mi/hr. How
much time did the dive last?
Need soon please!
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
What is speed?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

What is F = m x a in Newton's laws of motion?
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

1. The atomic number of an element is the same as the number of ______ that the element has.
Answer:
Explanation:
The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different atomic numbers.

Desarrollar un diagrama de flujo para un programa que solicite la base y la altura y calcule el área de un triangulo
Queremos crear un diagrama general para calcular el área de un triangulo.
Este será algo como:
Definir variablesPedirle al usuario que introduzca los valores deseados (de las variables).Leer los valores deseados y asignarlo a la variable correspondiente.Realizar la operación para calcular el área.Mostrar en pantalla el resultado.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.
Concluyendo, el diagrama en general sería:

a 16 Watt bulb is used for 5 hrs. what is the energy consumed by the bulb
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.

How does the distance traveled by the coin compare to its displacement after ten flips?
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.
