Answer: Viendo que los aviones viajan muy raramente exactamente en la misma dirección que el para compensar continuamente tanto la dirección como la velocidad del vientoLos vientos en contra significa exactamente lo contrario; se necesita más combustible y el vuelo llevará más tiempo condiciones secas y húmedas, pero el piloto tiene la decisión final sobre si.
Answer:
The acceleration of the box is 0.67 m/s²
Explanation:
Given that,
Mass of box = 30.0 kg
Horizontal force = 230 N
Friction force = 210 N
We need to calculate the acceleration of the box
Using balance equation
Where, F = horizontal force
=frictional force
m= mass of box
a = acceleration
Put the value into the formula
Hence, The acceleration of the box is 0.67 m/s²
The heat remains constant because there’s nothing to cool it down
Answer:
A. 20 N
Explanation:
weight of book is 2×10=20N
If you are instead clinging to a position halfway from the center to the outer rim of the Ferris wheel, YOUR ROTATIONAL SPEED WILL STILL BE 2 REVOLUTION PER MINUTE.
This is because, every part of the wheel is moving with the same speed, so it does not matter where you sit on the wheel, the rotation per minute will still be the same. It is just like travelling inside a motor car, it does not matter whether you are sitting in the front passenger seat or at the back, the speed of the car remains the same.
