Answer:direction
Explanation:
A vector must always have both sizes as well as direction, while on the other hand, any scalar quantity such as the mass of an object would only have magnitude but not direction.
What is a vector quantity?The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.
Examples of vector quantities are displacement, velocity acceleration, force, etc.
A scalar number, such as an object's mass, would only have magnitude but not direction, unlike a vector, which must always have both quantities and direction.

In a balanced chemical reaction, the total mass of the products always equals the
a.molar mass of the reactants.
c. total mass of the reactants.
b. atomic mass of the reactants.
d. proportional masses of the reactants.
Answer:
A balanced chemical reaction preforms the law of conservation of mass, when the total mass of the products always equals the total mass of the reactants.
Explanation:
In a balanced chemical reaction, the total mass of the products always equals the total mass of the reactants. Thus the total mass of the system is conserved.
What is mass conservation?According to the law of conservation of mass, mass can neither be created nor be destroyed. Hence, the total mass of the system is conserved. However, mass can be transformed into equivalent energy.
The balanced chemical equation of a reaction represents the perfect stoichiometric ratios of each reactants and products. The number of each elements in the product side must be equal to their number in the reactant side.
Therefore, the total mass of a products in a reaction is always equal to the total mass of reactants and no new atoms are created or any reactant elements are destroyed.

1 ) Starting from rest, a toy rocket accelerates at 12 m/sec/sec for exactly 4.0 seconds. It reaches 48 m/sec. Find the distance moved.
Coach Sweeney walks 24 yards to the north along the sideline, pauses, and walks 11
yards back to the south. Determine Coach's resultant displacement.
Answer:
13 yards north.
Explanation:
Distance and Displacement
A moving object constantly travels for some distance at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:
dtotal=d1+d2+d3+...+dn
This sum is obtained independently of the direction the object moves.
The displacement only takes into consideration the initial and final points of the path defined by the object in its moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.
Coach Sweeney walks 24 yards north and 11 yards back south. If Coach Sweeney started at the origin, the first walk ends in point (0,24). After going back 11 yards, the final point is (0,13).
Since the displacement only takes the initial and final points, we can say the resultant displacement was 13 yards north.

Position The figure shows a motorcyclist traveling east along a straight
road. After passing point B, the cyclist continues to travel at an average
velocity of 18 m/s east and arrives at point C2.8 s later. What is the
position of point ?
Answer:
s = 50.4 m
Hence, the point C is 50.4 m towards east from point B
Explanation:
Since, the motorcyclist travels at a constant speed in straight line towards east after point B. Therefore, we can use the following equation in this case:
s = vt
where,
s = distance covered = position of point C = ?
v = uniform speed of motorcyclist = 18 m/s
t = time interval = 2.8 s
Therefore,
s = (18 m/s)(2.8 s)
s = 50.4 m
Hence, the point C is 50.4 m towards east from point B

1. A skateboarder is skating over a circular bump. He is at the top of the bump and is
moving rightward. Is the normal force exerted on the skateboarder by the bump greater
than, less than, or equal to the weight of the skateboarder? Explain your reasoning.
Answer:
The normal force exerted on the skateboarder by the bump is less than the weight of the skateboarder
Explanation:
The given parameters are;
The location of the skateboarder = The top of the circular bump
The direction of motion of the skateboarder = Rightward
Therefore, given than the skateboarder has both horizontal angular motion (moving rightward) and vertical angular motion (over the bump), The effect of the weight of the skateboarder on the ground is reduced by the centripetal forces acting on the skateboarder and the normal force exerted on the skateboarder by the bump is equal to the reduced weight and is therefore less than the actual weight of the skateboarder.
The normal force exerted on the skateboarder is less than the weight due to the effect of centripetal force.
Given data:
The position of skateboarder is at top of the circular bump.
And direction of motion of Skateboarder is towards rightward.
Since, the skateboarder is undergoing the motion over the circular path, then it will have both horizontal angular motion (moving rightward) and vertical angular motion (over the bump).
The effect of the weight of the skateboarder on the ground is reduced by the centripetal forces acting on the skateboarder and the normal force exerted on the skateboarder by the bump is equal to the reduced weight and is therefore less than the actual weight of the skateboarder.
Thus, we can conclude that the normal force exerted on the skateboarder is less than the weight due to the effect of centripetal force.

Explanation:
The force needed to stop an object in motion is called?
force called friction
The force applied to object to stop its motion is known as frictional force.
Newton's first law of motion states that an object in a state of rest or uniform motion in a straight line, we continue in that form unless it is acted upon by an external force. This reluctance of an object to move or stop moving is known as the object's inertia. This inertia depends on the mass of the object.
When an object is finally in motion, the friction, between the object and the surface on which it is moving tends to limit the motion.
Thus, to stop an object in motion, we increase the frictional force between the object and the surface on which the object is moving
