Question

(Will give medal!!! Please answer asap.) Which of the following is true?
A. If an equal force is applied to two objects, the object with greater mass will accelerate more.
B. The greater the force that is applied to an object, the less it will accelerate.
C. Acceleration takes place when an unbalanced force acts upon an object.
D. When an object is traveling at constant speed and direction, it is accelerating.

Answer 1

the option c is the correct option
as in the first option, the obj with greater mass will accelerate less as F=ma if m is greater , to make the force a constant, a will decrease
next the b option, again F=ma here m is constant so if Fwill increase, the acceleration will increase
next
option c
if all the forces on the body are balanced, then the net force on the body will be zero and hence the acceleration of the body=0 but here there are unbalanced forces so the net forcewill not be zero

option d
acceleration is nothing but rate of change of velocity
here change in velocity is itself zero so rate of change is also zero so the acceleration will be zero

hope this helped you :)

Answer 2

Thanks so much. Can you help with another one?

Answer 3

yeah sure

Answer 4

actually i live in india and its midnight now and i need to wake up early in the morning so it will be better if you ask the question faster if you don't mind

Answer 5

@hottamolly you there???

Answer 6

Sorry, yes. Here's the question

Hannah just finished building a house of cards that stands four stories high. She is worried that it will fall down. Which of the following statements must be true?
A. If Hannah adds another card to the house of cards, then it will fall down.
B. If no unbalanced force acts upon the house of cards, then it will remain standing forever.
C. As long as nobody touches the house of cards, it will remain standing.
D. A house of cards is too fragile and must fall down eventually due to gravity

Answer 7

Also these two (only if you can)

9. Newton's first law of motion states that an object will keep a constant velocity unless acted upon by an unbalanced force.

To test this statement, Martin rolled a ball on a long, level street. The ball did not bump into any object, but it eventually came to a stop. How is this possible?
A. The unbalanced force that caused the ball to stop was friction.
B. Newton's first law of motion only holds true in space, not on Earth.
C. Every moving object must come to a stop because energy cannot be destroyed.
D. Martin did not roll the ball hard enough, which caused the ball to eventually stop rolling.
10. Which of Newton's laws of motion is best illustrated by the dribbling of a basketball?
A. Newton's first law
B. Newton's fourth law
C. Newton's second law
D. Newton's third law

Answer 8

i'm on it

Answer 9

the answer for 9. is A
if you have an idea about inertial and non-inertial reference frames, then you may know that newtons laws are valid for all observations made from inertial referene frames and earth is considered to be an inertial ref. frame well its very deep you'll study it in depth in the higher classes

the answer for the questin 10 is newtons third law
as we drible the basketball and it comes in contact with our hand , it exerts a force on our hand i.e. normal force and our hand applies the normal force of same magnitude on the basket ball and same happens between the basketalll and the ground. if the normal force would be absent, it would go through our hand and the ground(lol).


hope this is helpful
do you have any more questions?

Answer 10

One more.

Hannah just finished building a house of cards that stands four stories high. She is worried that it will fall down. Which of the following statements must be true?

C. As long as nobody touches the house of cards, it will remain standing.
D. A house of cards is too fragile and must fall down eventually due to gravity

Answer 11

the answer is b according to me and you can get it by newtons first law
