An unbalanced force can cause an object to:

Physics
1 answer:
mestny [16]3 years ago
4 0
The correct options are:
<span>A. change the direction of its velocity.
B. change the magnitude of its velocity.

For instance, A is true in case of a uniform circular motion: if there is an unbalanced force that acts as centripetal force, this force changes the direction of the velocity of the object (it makes it turning in a circular path) but not its magnitude.

Instead, B is true for instance when an unbalanced force F is applied in the same direction of motion of the object: the object will experience an acceleration given by F=ma, and so since the object accelerates, the magnitude of its velocity will change.</span>

In experimental design: What are<br> the two groups?
sp2606 [1]

Answer:

The correct answer is : a special type of experimental design where subject divides in two groups according their treatment setting.

Explanation:

A two group is a experimental design two groups are the two different groups of subjects divided by the researcher for comparing the data and result to establish relation in variables.

In normal case, one of the two groups one is a group of subjects who get treatment known as experiment or treatment group while other group is known as control group without treatment.

Thus, the correct answer is : a special type of experimental design where subject divides in two groups according their treatment setting.

During 9.97 seconds a motorcyclist changes his velocity from v1,x = -36.5 m/s and v1,y = 10.9 m/s to v2,x =-21.9 m/s and v2,y =
svetoff [14.1K]

Average acceleration is defined as

a = \frac{v_f - v_i}{t}

here

v_f = final\: speed

v_i = initial\: speed

t = time

now for x direction we can say

a_x = \frac{v_{2x} - v_{1x}}{t}

a_x = \frac{-21.9 + 36.5}{9.97}

a_x = 1.46 m/s^2

Similarly for Y direction

a_y = \frac{v_{2y} - v_{1y}}{t}

a_y = \frac{27.5 - 10.9}{9.97}

a_y = 1.66 m/s^2

so above is the acceleration in x and y directions
