i think it is c if not im sorry if im wrong
Explanation:
In order to ride a bike up a hill with increasing speed—
the rider’s pedal force must be less than friction and the force of gravity
the rider’s pedal force must be equal to than friction and the force of gravity
the rider’s pedal force must be greater than friction and the force of gravity
It is impossible to ride up a hill with increasing speed.
Answer: the rider’s pedal force must be greater than friction and the force of gravity
Explanation:
This is because if the pedal force was less, you would go slower, and it is obviously not impossible to ride up a hill without increasing speed. But if the force was greater, your speed would increase.

Several objects were dropped from a balcony. Using the data below, determine which statements must be true regarding the rate of force of each falling object. Neglect (ignore) air resistance. Object Mass Diameter Height of drop Tennis Ball 0.06 kg 6.6 cm 5 m Baseball 0.15 kg 74 cm 5 m Bowling Ball 5 kg 21 cm 5 m Golf Ball 0.04 kg 4.3 cm 5 m Statement 1: All balls hit the ground at the same time Statement 2: All balls hit the ground with different forces Statement 3: The bowling ball hit the ground first and the tennis and golf ball hit the ground last Statement 4: It is not possible to tell how much force each ball hit the ground with
Answer:
statement three and statement 2
Explanation
since they are weighted different, they will have more or less force (more mass=more force), also the heavier an object, the greater its acceleration while falling.
help pleas!!!!
The food coloring spread _______ in the hot water. *
Faster
Slower
Faster
Explanation:
The food coloring travels through hot water better due to the molecules having better energy and move faster than cold water molecules.
Suppose scientists discover two new moons.The average surface temperature of one of the moons is –180°C, but the temperature can reach 1500°C near active volcanoes.
Sulfur dioxide (SO2) has been detected on this moon. SO2 has a melting point of –72°C and a boiling point of –10°C. Where will SO2 be gas?
A.
In the center of active volcanoes
B.
Away from active volcanoes
C.
Near active volcanoes

A heavy box is dropped from the roof of a small building and is traveling to the ground. Which claim about the forces acting on the box must be true?
Choose 1 answer:
A. There are no forces on the box.
B. There is no net force on the box.
C. There is a net force on the box.
D. There is not enough information.
Answer:
C. There is a net force on the box.
Explanation:
If the box was stationary, sitting on the roof, the correct answer choice would be A. In this scenario, the box is fallign downward, meaning that there is a net force pushing the box downward.
Answer:
C: there is a net force on the box

According to Newton’s second law of motion, the relationship between an object's mass (m), its acceleration (a), and the applied force (F) is F = ma. How does this law apply to the sport of bowling?
When the pins are correctly aligned, their mass and acceleration will keep the ball from going into the gutter.
When the bowling ball is rolling down the lane, the mass of the ball on the floor makes the pins become unstable, allowing the acceleration of the ball to knock down the pins.
When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins
When the bowling ball hits the pins, the ball has a mass, so it will exert acceleration on the pins and knock them down.
Answer:
When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins.
Explanation:
That is because you accelerate the ball with a force when you roll it, and the mass of the ball has a force that knocks down the pins.
Answer:
When the bowling ball is rolled with a force, this accelerates the ball. That acceleration, when combined with the mass of the ball, produces a force that knocks down the pins. when the bowling ball id rolling with a force, this accelerates the ball. this is why the ball is combinding with the force of the mass of the ball.
Explanation:
bonjour HELPPPP :) LOL
In which of the following situations will the ball have the greatest acceleration?
A golf ball with a mass of 0.045 kg is struck with a force of 1 N
A baseball with a mass of 0.142 kg is hit with a force of 5 N.
A soccer ball with a mass of 0.45 kg is kicked with a force of 20 N.
A bowling ball with a mass of 7.2 kg is thrown with a force of 60 N.
Answer:
your answer should be D hope this helps!
