Answer:

50 pounds

Explanation:

A toe board is a 2 inch x 4 inch safety wooden board used when adding roofing to a house. According to my research on the limits for toe boards, I can say that a toe board can withstand a force of at least 50 pounds applied in any downward or outward direction at any point without failure. This has been tested extensively by professionals before sale.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

3. If a certain quantity of gas has a volume of 30 cm3 at a pressure of 1 × 105 Pa, what is its volume when the pressure is
arlik [135]

We know that:

                             P_{1}V_{1}= P_{2}V_{2}               .......(1)

Given at P_{1}=30cm^3 , V_{1}=10^5Pa

a)

When P_{2}=2*10^5Pa , V_2=?

Using equation (1)

                                    30*10^5=2*10^5*V_2

                                     V_2=30/2=15cm^3

b)

When P_2=5*10^5Pa, V_2=?

using equation (1)

                                     30*10^5=5*10^5*V_2

                                    V_2=30/5=6cm^3

How much energy is transported across a
irina1246 [14]

Explanation:

Let us assume that Z is the energy transported across an area of 1.00 cm^{2} per hour by an electromagnetic wave with an r.m.s speed of 21.5 V/m.

Therefore, first we will calculate the current as follows.

                  I = \frac{E_{rms^{2}}}{c \times \mu_{o}}

                    = \frac{10^{-4} \times 3600 \times (21.5)^{2}}{3 \times 10^{8} \times 4 \times 3.14 \times 10^{-7}}

                    = 0.441 J

Therefore, we can conclude that 0.441 J energy is transported across a given EM wave.

Viscosity: Blood is about 4 to 5 times ____________ viscous than water. Viscosity of blood depends upon the amount of dissolved
kherson [118]

Answer:more, increased

Explanation:

Blood is four to five times more viscous than water.

Viscosity depends upon dissolved substances in blood and it increases as the amount is increases or if the fluid in the blood decreases.

Viscosity is the resistance offered by liquid to the flow and it also depends upon temperature and it decreases with increase in temperature.
