Answer:
Explanation:
The signals sent from the earth, travel at the speed of light, therefore the travel time of the signal between the earth and neptune, can be calculated with the following equation, which relates time, speed and distance:
The time elapsed is approximately 4.41 hours
Answer:
Explanation:
The total force exerted by the man on the chair is equal to his weight:
where m=95.0 kg is the man's mass and g=9.8 m/s^2. Substituting,
Since there are 4 legs, we can assume that the force is equally distributed over the 4 legs; so the force supported by each leg is
The radius of each leg is , so the area of each leg is
And the pressure exerted on each leg is equal to the ratio between the force supported by each leg and the area:
It is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game.
<h3>
What is a motor crash?</h3>
A motor crash is the event in which a motor vehicle is involved in a collision amongst another motor vehicle, pedestrian, animal, or stationary object.
<h3>Impact of motor crash</h3>
A motor crash can cause the following;
- total damage of the car
- breaking of bones of the driver
- damage of properties colliding with the car
Thus, it is not possible for Leon to be involved in a motor crash, in which the car is demolished without sustaining an injury except Leon is playing a video game. In the video game he will not be involved physically with the motor crash.
