Answer:

47911.1 pa

Explanation:

The SI base unit of pressure is pascal, which is N/m^2.

2200 kg is 2200*9.8=21560 N, and 4500 cm^2=4500/10000=0.45 m^2.

So the total pressure exerted on the ground (!!) is 21560/0.45= 47911.1 Pa.

Answer:

pressure =

47911.11 \:  \: pascals

Explanation:

here's the solution :-

force = weight of elephant.

=》f = mg

( where m = mass and g = acceleration due to gravity )

=》f = 2200 × 9.8

=》force = 21560 N

( note : acceleration due to gravity is also taken as approximate 10 , unless it is not mentioned in question we are taking it as 9.8 )

Area of footprint of elephant = 4500 cm^2

=》

\frac{4500}{10000} \:  meter {}^{2}

=》0.45 m^2

now,

=》pressure = mass ÷ area in contact

=》

p =  \frac{21560}{0.45}

=》

p = 47911.11 \: pascals

Answer:

If one astronaut used more force, then that one would be faster than the other. The independent variable is force. The dependent variable is speed.

Explanation:

Force is what is to be changed. Speed is what is being measured.

A 0.105 L sample of an unknown HNO 3 solution required 35.7 mL of 0.250 M Ba ( OH ) 2 for complete neutralization. What is the c
oksano4ka [1.4K]

Answer: 0.17M

Explanation:

The equation for the reaction is :

2HNO3 + Ba(OH)2 —> Ba(NO3)2 + 2H2O

From the balanced equation, we obtain :

nA = mole of acid = 2

nB = mole of the base = 1

From the question, we obtain:

Va = Vol. Of acid = 0.105L

Ma = conc. Of acid =?

Vb = Vol of base = 35.7 mL = 0.0357L

Mb = conc. of base = 0.25M.

We solve for the conc. of the acid using:

MaVa / Mb Vb = nA / nB

(Ma x 0.105) / (0.25x0.0357) = 2

Cross multiply to express in linear form. We have:

Ma x 0.105 = 0.25 x 0.0357 x 2

Divide both side by 0.105. We have

Ma = (0.25 x 0.0357 x 2) / 0.105

Ma = 0.17M

Therefore the concentration of the acid(HNO3) is 0.17M

What describes a change in velocity?
siniylev [52]
Acceleration can be described as changes in speed, changes in direction, or changes in both. Acceleration is a vector.
