Answer:
The answer is 218
Explanation:
Weight = mass * gravitational acceleration
weight is represented by F
F = 25kg (8.7)
(I'm pretty sure that you don't have to include the meters per second/per second thing)
The potential energy of a 30N ball on the ground will be zero. With respect to height, h. Potential energy will be calculated like this. P=mgh. So if its on the ground relatively speaking the h=0. Thus inputting into the above formula. P=0.
Answer:
Distance is 13m and Displacement is 9m
Explanation:
All of the following would be questions that could be scientifically investigated except A.
That is an opinion and cannot become a fact.
The speed of an object that travels 400 km in 5 hours, would be calculated simply by taking the distance of 400 and dividing it by the number of hours 5.
400 km/5 hours = 80km/hr.
The speed is 80 km/hr.
