I can't tell right away. The elevator's limit is given in terms of mass, but the four people are listed in terms of their weights. In order to compare them, we'll have to convert one or the other.
The total of the four people's weights is:
John . . . . . . . 850N
Betty . . . . . . . 530N
Robert . . . . . . 740N
Alice . . . . . . . .610N
Total . . . . . . 2,730N
The elevator can't accept more than 300 kg of mass.
The weight of any mass is (mass) x (gravity).
On Earth, 300kg weighs (300kg) x (9.8 m/s²) = 2,940 N.
Wonderful !
2,730N is less than 2,940N.
<em>Yes !</em> According to Otis' engineers, John, Betty, Robert and Alice <em>can safely ride the elevator together</em>, (although Betty and Alice may have a different opinion).
The coefficients will be 1, 2, 1, 1. Everything will remain the same but put the coefficient of 2 in front of NH4OH
Answer:
Electrical Energy and Sound Energy
Explanation:
Answer:
The acceleration towards the center will be
Explanation:
Given the running track is an oval shape, and the diameter of each half-circle is 74 meters.
Also, the runner took 1 minute and 40 seconds to complete 400 m one round of the track.
We need to find the acceleration towards the center.
First, we will find the speed.
Where is the speed.
is the distance covered by the rider that is 400 meters.
is the time taken by the rider to complete the lap which is 1 minute and 40 seconds. seconds.
So,
And
Where is the acceleration towards the center.
is the radius which will be the half of the diameter 74 meters.
Hence, the radius will be 37 meters.
So, the centripetal acceleration of the rider will be
Answer:
Explanation:
Let the initial speed of the ball is given as
then angle of inclination is given as 33 degree
now its two components of velocity is given as
now the two positions with time given as
now when it hit the wall so we will have
now from above two equations we will have
now from above equations again
