Answer:

6.67 s

Explanation:

Assuming that the velocity is constant, then the governing equation in this case is:

Distance = Velocity x Time

Time = Distance / Velocity

= 100 / 15

= 6.67 s

Responding to the environment by maintaining a stable internal environment despite changing external conditions is

Debora [2.8K]

Chinook salmon work to maintain a stable internal environment despite changes in external conditions by the process called homeostasis. Homeostasis is important because salmon, like all living organisms, depend on the proper functioning of its cells to ensure its survival and the ability to reproduce.

Perception Distance + Reaction Distance + Braking Distance = _____________.

scZoUnD [109]

Answer:

option B) is correct

Explanation:

perception distance is the distance traveled by the vehicle when the driver perceive the hazard situation.

reaction distance is the distance traveled by the vehicle after seeing the hazard situation and reacting to it.

Braking Distance is the distance traveled by the vehicle after applying the brake.

so, the sum of Perception Distance + Reaction Distance + Braking Distance is called the total stopping distance

hence option B) is correct .

Since force is dp/dt, the force due to radiation pressure reflected off of a solar sail can be calculated as 2 times the radiati

QveST [7]

Answer:

8.67×10⁻⁶ N/m²

Explanation:

p = Momentum of a photon

E = Energy of a photon

c = Speed of light

I = Intensity of light

Force = dp/dt

$p=\frac{E}{c}$

$\\\Rightarrow F=\frac{\frac{dE}{dt}}{c}$

As given in question

$F=2\frac{\frac{dE}{dt}}{c}$

Now F/A = Pressure

$P=\frac{2I}{c}\\\Rightarrow P=\frac{2\times 1300}{3\times 10^{8}}\\\Rightarrow P=8.67\times 10^{-6}\ N/m^2$

∴ Magnitude of the pressure on the sail is 8.67×10⁻⁶ N/m²

belka [17]

Answer:

v = 330.7 m/s

Explanation:

Let say initially the speed of two blood cells is v and they are far apart from each other

when they come to the closest distance to each other then in that case the initial total kinetic energy of two blood cells will convert into electrostatic potential energy of the cells

So we can say

$\frac{1}{2}mv^2 + \frac{1}{2}mv^2 = \frac{kq_1q_2}{2r}$
