A 20 kg truck drives in a circle of radius 4 m at 10m/s. What causes

Physics
1 answer:
jek_recluse [69]2 years ago
6 0

Answer:

Normal force

Explanation:

  • The force is centipetral force

Calculating :-

  • Mass=m=20kg
  • Radius=r=4m
  • Velocity=10m/s=v

We know

\boxed{\sf F_c=\dfrac{mv^2}{r}}

\\ \sf\longmapsto F_c=\dfrac{20(10)^2}{4}

\\ \sf\longmapsto F_c=\dfrac{20(100)}{4}

\\ \sf\longmapsto F_c=\dfrac{2000}{4}

\\ \sf\longmapsto F_c=500N

Lelu [443]

what? I guess:

  • practice different habits. If you fail don't give up.

Argon makes up 0.93% by volume of air. Calculate its solubility (in mol/L) in water at 20°C and 1.0 atm. The Henry's law constan
vladimir2022 [97]

Answer:

S= 1.40x10⁻⁵mol/L

Explanation:

The Henry's Law is given by the next expression:

S = k_{H} \cdot p (1)

<em>where S: is the solubility or concentration of Ar in water, k_{H}: is Henry's law constant and p: is the pressure of the Ar </em>

<u>Since the argon is 0.93%, we need to multiply the equation (1) by this percent:</u>

S = 1.5 \cdot 10^{-3} \frac{mol}{L\cdot atm} \cdot 1.0atm \cdot \frac{0.93}{100} = 1.40 \cdot 10^{-5} \frac{mol}{L}

Therefore, the argon solubility in water is 1.40x10⁻⁵mol/L.

Have a nice day!

A typical mattress has a network of springs that provide support. If you sit on a mattress, the springs compress. A heavier pers
GenaCL600 [577]

Answer:

Explanation:

Spring has a tendency to store energy in them and deform its shape when force is applied on it. Once the applied force is removed it regains its original shape and size.

It is in helical shape and is used in mattress to give structure and support. Spring have elastic nature and follows spring forces, F = k * x

where is the applied force, k is the spring constant and x is the amount of extension.

When a heavier person sits on a mattress, more weight is applied on springs and they form coils, as weight is removed they regains its shape again.
