Answer:

27 m/s

Explanation:

Given:

v₀ = 15 m/s

a = 3 m/s²

t = 4 s

Find: v

v = at + v₀

v = (3 m/s²) (4 s) + (15 m/s)

v = 27 m/s

Answer:

The final speed of the taxi is 27 m/s.

Explanation:

Given data

  • Initial speed (v₀):  15 m/s
  • Acceleration (a): 3 m/s²
  • Time (t): 4 s

We can find the final speed (vf) using the following kinematic expression.

vf = v₀ + a × t

vf = 15 m/s + 3 m/s² × 4 s

vf = 15 m/s + 12 m/s

vf = 27 m/s

The final speed of the taxi is 27 m/s.

What if we all jumped at the same time?
Anit [1.1K]
Technically, this delivers a lot of energy into the Earth, but it’s spread out over a large enough area that it doesn’t do much more than leave footprints in a lot of gardens. A slight pulse of pressure spreads through the North American continental crust and dissipates with little effect. The sound of all those feet hitting the ground creates a loud, drawn-out roar which lasts many seconds.

In terms of instrument sensitivity, explain why he choice of wavelength on the colorimeter is important
elena55 [62]
Colorimeters function by passing colored light through a specific optical filter. The choice of wavelength on the colorimeter is important in terms of instrument sensitivity since the device gives the most sensitivity which can be used as a test factor in determining the lower detection limit.

Two bodies, one hot and the other cold kept in vacuum.what will happen to the tempreture of bodies after some time.
Dovator [93]
Hot body will lose heat from it, and that heat will goes out from it through radiation, so it's temperature will decrease after some time.

In same manner, cold body will take the heat, and it's temperature will increase

Hope this helps!
