Three objects have velocities that vary with time
Solnce55 [7]

#21

  • initial velocity=u=5m/s
  • Time=t=2s
  • Acceleration=a=1.3m/s²

According to first equation of kinematics

  • v=u+at
  • v=5+1.3(2)
  • v=5+2.6
  • v=7.6m/s

#22

#a

  • v1=2+3(3)=2+9=11m/s
  • v2=-8-4(3)=-20m/s
  • v3=1-5(3)=-14m/s

The order is

  • v2<V3<v1

#b

for speed find absolute velocity

  • S1=|11|=11m/s
  • S2=|-20|=20m/s
  • S3=|-14|=14m/s

So order is

S1<S3<S2

A car engine has power than a horse because a car engine does the same amount of work in time. Yasmin and Raj each had 10 boxes
labwork [276]

Answer:

A car engine has more power than a horse because a car engine does the same amount of work in time. Yasmin and Raj each had 10 boxes of equal weight to stack next to each other on the same shelf, at the same height and in the same arrangement. Yasmin completed the task in 2 minutes, while Raj took 3 minutes to stack his boxes. Raj applied less power than Yasmin because his stacking took more time to do the same amount of work.

How many focal points does a lens have?
VMariaS [17]

Answer and Explanation:

Every lens have two focal points each focal point is present on the either side of the lens. In lenses when light comes from the infinite it passes through the focal point it is true for both converging as well as diverging lens. In mirror there is only one focal point as it one face is covered but in lens light can pass through side of the lens so it has two focal point

How does the wave model of electrons orbiting the nucleus account for discrete energy values?
o-na [289]

Explanation:

When treating the electron as a wave, the concept of electrons orbiting the nucleus allows for the distinct energy levels.The diameter of electron orbits matches the orbit radii which also discrete the energy levels.

The small number of deflected particles were repelled from powerful heavy positively charged central cores which is known as the atomic nucleus.
