How does that motion change for the object if the forces on the object are unbalanced?
When the forces on the object are unbalanced, the object will move in the direction of the greater force.
What is Newton's first law of motion?Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force and the object will tend to move in the direction of the applied force.
What is Newton's second law of motion?Newton's second law of motion states that the force applied to a body is directly proportional to the acceleration of the body.
F = ma
Unbalanced forces on a bodyIf the net force acting on a body is greater than zero, the body will tend to move in the direction of the greater force.
Thus, when the forces on the object are unbalanced, the object will move in the direction of the greater force.

21. A fisherman catches two sturgeons. The smaller of the two has a measured length of 93.46 cm (two dec- imal places and four significant figures), and the larg- er fish has a measured length of 135.3 cm (one deci- mal place and four significant figures). What is the total length of the two fish?
Answer:
135.3 cm + 93.46cm
= 228.76 cm
So total length of two fish is 228.76
A 4.5 kg box is being pulled by a girl using a string that makes an angle of 20° horizontal. Find the force of friction if the force exerted on the string is 15 N and the coefficient of friction is 0.5.

Fcoso-f =ma. F= ma 15 = 4.5 a then get acceleration. Fcoso- umg = ma then get friction
A box is in contact with a floor with a coefficient of friction of 0.50. If the box has a normal force of 500N, what force do have to push with to move the box? HELPPP
Answer:
250N
Explanation:
Coefficient of friction=frictional force/Normal force
coefficient of friction= 0.5Normal force(R)= 500NFrictional force (Fr)= ?0.5= Fr/500N
Fr= 500N×0.5 = 250N
Fr= 250N
A mason is shot with a constant speed of 7.5 x 10²m/sinto a region, when an electric field produces acceleration on the mason of magnitude 1.5 x 1025 ms-2 directed opposite to the velocity. Find the time taken (b) the distance covered by the mason before coming to rest and (c) the time for which it remains at rest.
Answer:
Distance, d = 0.1 m
It is given that,
Initial velocity of meson,
Finally, the meson is coming to rest v = 0
Acceleration of the meson, (opposite to initial velocity)
Using third equation of motion as :
s is the distance the meson travelled before coming to rest.
So,
s = 0.1 m
The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.

Which line on the graph represents the greatest positive acceleration?
D
A
B
C
Answer:
I think it's B, if that's wrong I apologize. You might want to do more research on it and find the correct answer if you can, if it's right then you could like my comment, so others know if not give it 1 star, keep it low lol.
Explanation:
The line that represents the greatest positive acceleration is A.
In a velocity-time graph, the slope of the line represents the acceleration. The greater the slope, the greater the acceleration. Line A has the steepest slope, so it represents the greatest positive acceleration.
Line B has a positive slope, but it is not as steep as line A. Line C has a negative slope, which means it represents negative acceleration, or deceleration. Line D is a horizontal line, which means it represents a constant velocity, or zero acceleration.
Therefore, the line that represents the greatest positive acceleration is A.

What is the magic triangle used for in science? 10 points
Speed, distance and time can be calculated using a magic triangle. D (the distance) goes in the top of the triangle, S (speed) goes in the bottom left of the triangle and T (time) goes in the bottom right of the triangle.
A cannonball is fired from a cliff that is 50 meters above the ground. The cannonball is fired horizontally with a speed of 120 meters per second.
Calculate the horizontal distance that the cannonball will travel.
The horizontal distance that the cannonball will travel is 383.33m
In order to find the horizontal distance, we will use the formula for calculating the range expressed as:
[tex]R = u\sqrt{\frac{2H}{g} }[/tex] where:
u is the velocity
H is the height
g is the acceleration due to gravity
[tex]R = 120\sqrt{\frac{2(50)}{9.8} }\\R = 120\sqrt{\frac{100}{9.8} } \\R=120\times 3.1943\\R=383.33m[/tex]
Hence the horizontal distance that the cannonball will travel is 383.33m

Bettina was sick for several weeks, and her slow recovery has made her realize that she is not as healthy as she thought she was. She has never been fond of exercise and is intimidated at the thought of going to a gym. Walking seems manageable, and there are some hills in her neighborhood. But she knows that is not aerobic exercise. Is this a good place to start?
OPTIONS:
A.
No, walking is neither aerobic nor anaerobic exercise.
B.
No, exercise that is not aerobic never does much good.
C.
Yes, but she will not have any health benefits unless she escalates it.
D.
Yes, she can slowly improve her capacity and move to aerobic exercise later.
Yes. Walking the hills in her neighborhood is a wonderful place to start.
D. She can slowly improve her capacity and move to aerobic exercise later.
Yes, she can slowly improve her capacity and move to aerobic exercise later. The correct option is (D).
Even if it isn't initially aerobic, starting with walking is a wonderful place to start, especially if Bettina isn't used to exercising frequently. Walking is a low-impact activity that is simple to fit into daily life and can be used as a gentle introduction to developing a habit of physical activity.
Even while walking isn't typically thought of as an aerobic workout, it nevertheless has several health advantages, including enhancing cardiovascular health, boosting energy, lowering stress, and aiding in weight management. Bettina can eventually increase the length and intensity of her walks to make them aerobic as she steadily increases her endurance and fitness level through walking.
Hence, the correct option is (D). Yes, she can slowly improve her capacity and move to aerobic exercise later.
