Answer:
Polished surfaces reduce heat loss
Answer:
<h3>The answer is 40 N</h3>
Explanation:
The force acting on an object can be found by using the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 4 kg
acceleration = 10 m/s²
So we have
force = 4 × 10
We have the final answer as
<h3>40 N</h3>
Hope this helps you
Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)
Final velocity (
V2) = 0 ft/s because the car stops
Time (
t) = 4 seconds
a =

a =

a =

a = -22
Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')

Answer:

Explanation:
Hola.
En este caso, dado el volumen y densidad de cada barra, podemos calcular el peso de cada una en toneladas con la correspondiente conversión de 1 ton = 1000 kg:

De este modo, si el camión resiste 10 toneladas, el número de barras resulta de la división entre la capacidad del camión y el peso por barra:
