Answer:
471 N
Explanation:
Weight is just another word for the force of gravity.
Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth (g-9.81 m/s2)
so we can simply say
weight =mass * gravitaitonal acceleraition
= 48 * 9.81
=470.88 N
= 471 N
Answer:
it will be curved as in deceleration
Explanation:
Pressure = (total force) / (Area)
10,000 Pa = (1,000 N) / (Area)
Multiply each side by (Area) :
(10,000 Pa) x (Area) = 1,000 N
Divide each side by (10,000 Pa) :
Area = (1,000 N) / (10,000 Pa)
<em>Area = 0.1 m² </em>
Question
A car travels 300 km in the first 3 hours of a trip. Then it hits traffic and travels only 60 km during the last hour. What is the average speed of the of the car?
300 + 60 = 360 Km (total travel)
3 + 1 = 4 hours (total time)
360 : 4 = 90
C.) 90 Km/h is your answer
Answer:NO
Explanation:
No, because as it swings it is mechanical energy that changes from almost completely potential energy to almost completely kinetic energy and thermal and sound.
