What is the action force and the reaction force when you sit down on a chair

1 answer:

4 0

The action force is when you are putting your weight on the chair when you are sitting down. the reaction force is the force exerted by the chair that pushes up on your body and is equal to your weight.

How does convection play a role in hurricanes

Sonbull [250]

Answer:

Convection is what keeps the hurricane going in till the storm hits land.

Explanation:

Convection is the warm, moist current that rises above sea level and as it cools into water vapor it releases energy which a hurricane runs on. Once the hurricane hits land it continues to lose energy to keep it going because there's no convection from the sea currents rising above sea level to release energy.

Hope this helps.

Are there any steps of the rock cycle that do not connect directly to one another

dybincka [34]

Answer:

The three main rock types are igneous, metamorphic and sedimentary.

The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.

Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

Automobile which is being towed at constant velocity up the incline using the cable at c. The automobile has a mass of 5 mg and

Simora [160]

The value of the normal reaction force will be 4.65 kN and 31.76 kN.

<h3>What is force?</h3>

Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.

The normal force on the car is,Na= Nb =1 kN

The force of the cable on the car is,F=1 kN

The force of the gravity is,W=mg

The balancing equation of force;

$\rm N_A+N_B+F sin \theta_2 -mg cos \theta_2 =0 \\\\ \rm -Fcos \theta_2 +mg sin \theta_1 =0 \\\\ Fcos \theta_2 \times a -F sin \theta_2 \times b -mg cos \theta_1 \times c -mg sin \theta_1 \times e +N_B (c+d)=0 \\\\ N_A+N_B+F sin 30^0 - 5 \times 9.81 cos 30^0 =0 \\\\ -$

Putting the value further;

$\rm N_A+N_B+F sin 30^0 - 5 \times 9.81 cos 30^0 =0 \\\\ -F cos 30^0 + 9.81 sin 20^0 =0 \\\\ F cos 30^ 0 (0.6)-F sin30^0 (1.5)-(5 \times 10^6) \times 9.81 \times cos 20^0 (1)-(5)(9.81)sin 20^0 +N_B \times 1.75 =0$

Solving the equation, we get;

$\rm F_A = 19.37 \ kN \\\\ N_A=4.65 \ kN \\\\ N_B=31.76 \ kN$

Hence, the value of the normal force swill be 4.65 kN and 31.76 kN.
