A 3.63.kgkg chihuahua charges at a speed of 3.3m/s3.3m/s. What is the magnitude of the average force needed to bring the chihuah
sergiy2304 [10]

Answer:

23.96 N

Explanation:

From the question given above, the following data were obtained:

Mass of Chihuahua (m) = 3.63 kg

Velocity (v) = 3.3m/s

Time (t) = 0.50 s

Force (F) =?

Next, we shall determine the acceleration of the Chihuahua. This can be obtained as follow:

Velocity (v) = 3.3m/s

Time (t) = 0.50 s

Acceleration (a) =?

a = v/t

a = 3.3/0.5

a = 6.6 m/s²

Thus, the acceleration of the Chihuahua is 6.6 m/s².

Finally, we shall determine the force need to stop the Chihuahua as shown below:

Mass of Chihuahua (m) = 3.63 kg

Acceleration (a) = 6.6 m/s².

Force (F) =?

F = ma

F = 3.63 × 6.6

F = 23.96 N

Therefore, a force of 23.96 N is needed to stop the Chihuahua.

A force of 20 newtons is exerted on a chair from its right and a force of 12 newtons is applied from
tankabanditka [31]

Answer:

The net force acting on the chair is 8 newtons, and the chair moves toward the left.

Explanation:

We can better understand this problem if we analyze it through a free body diagram. This free body diagram is attached as an image.

If we make a sum of forces acting over the chair we can find -20 + 12 = -8 [N]

The minus sign indicates that the chair is moving to the left.

An empty jar is pushed open-side down into water so that trapped air cannot escape. As it is pushed deeper, the buoyant force on
Pavlova-9 [17]

As it is pushed deeper, the buoyant force on the jar will decrease. The correct option is B

<h3>What is buoyant force ?</h3>

The upward force applied to an object that is fully or partially submerged in a fluid is known as the buoyant force. Upthrust is another name for this upward thrust. A body submerged partially or completely in a fluid appears to shed weight, or to be lighter, due to the buoyant force.

The fluid under which an object is submerged exerts pressure, which is what generates the buoyancy force. Because a fluid's pressure rises with depth, the buoyancy force is always upward.
