Answer 4

A motorcycle goes north at 40 miles per hour. A car goes south at 40 miles per hour on the same street. Which statement is true?(1 point) Responses The vehicles are going in opposite directions, so their speed is not the same. The vehicles are going in opposite directions, so their speed is not the same. The vehicles have the same speed, but different velocity. The vehicles have the same speed, but different velocity. The vehicles have the same velocity, but not the same speed. The vehicles have the same velocity, but not the same speed. The vehicles have the same speed and velocity.

Answer 5

What do unbalanced forces do?(1 point) Responses Unbalanced forces cause an object’s motion to change. Unbalanced forces cause an object’s motion to change. Unbalanced forces can make an object move in the opposite direction of the force that is applied. Unbalanced forces can make an object move in the opposite direction of the force that is applied. Unbalanced forces cannot change an object’s direction. Unbalanced forces cannot change an object’s direction. Unbalanced forces allow an object’s motion to stay the same.

Answer 7

so which one

Answer 8

Which choice represents velocity?(1 point) Responses 35 m/s 35 m/s 4 g/mL 4 g/mL 12 m/s2 12 m/s2 15 km/hr west

Answer 9

In order for both the golf ball and the bowling ball to reach 15 mph, the scientist would have to apply a different amount of force or energy to each ball.

Since the bowling ball is much heavier than the golf ball, it has a higher inertia. This means that it requires more force to accelerate it to the same speed as the golf ball. To move the bowling ball to reach 15 mph, the scientist would have to apply a larger force or exert more energy compared to the golf ball.

Additionally, due to the differences in size and surface area, the scientist may also need to consider factors like air resistance or friction. However, assuming these factors are negligible, the main difference lies in the amount of force or energy required to move each ball to the desired speed.

Answer 10

To make both the golf ball and the bowling ball reach 15 mph, the scientist would need to apply a stronger force or energy to the bowling ball. Since the bowling ball is heavier, it requires more force to accelerate to the same speed as the golf ball.

Answer 11

Inertia plays a crucial role during a car accident. Inertia is the resistance of an object to change its state of motion. When a car is in motion, the passengers inside it are also in motion. In the event of a sudden stop or collision, the passengers tend to continue moving forward due to their inertia.

Seatbelts are a vital tool in place to keep us safe during a car accident. They restrain our bodies and prevent us from being thrown forward with full force, reducing the risk of severe injury or ejection from the vehicle. Seatbelts help overcome our inertia by providing an opposing force to keep us restrained and slow down our motion during an accident.

Airbags are another safety feature designed to protect us during a car accident. They help to reduce the impact force on our bodies by quickly inflating and providing a cushioning effect. Airbags work together with seatbelts to absorb and distribute the kinetic energy, minimizing the potential for severe injuries.

Additionally, car manufacturers incorporate various safety technologies, such as crumple zones and anti-lock braking systems (ABS), to further enhance passenger safety during a collision. Crumple zones are specific areas of the vehicle designed to deform and absorb the impact energy, thus reducing the force experienced by the occupants. ABS helps to prevent the wheels from locking up during braking, allowing the driver to maintain control and avoid accidents.

In summary, during a car accident, inertia tends to keep objects, including passengers, in motion. To keep us safe, seatbelts and airbags are in place to overcome inertia and reduce the forces exerted on our bodies. Car manufacturers also implement additional safety technologies to enhance passenger protection during accidents.

Answer 12

During a car accident, airbags play a vital role in keeping us safe. Airbags quickly inflate when a collision occurs, creating a cushion between us and the hard surfaces inside the vehicle. They help reduce the impact force, protecting our heads, chests, and other body parts from hitting the steering wheel or dashboard. Airbags work together with seatbelts to enhance our safety by absorbing and distributing the energy from the crash. They are an important safety feature that significantly reduces the risk of severe injuries in car accidents.

Answer 13

The statement "The vehicles are going in opposite directions, so their speed is not the same" is true. The vehicles have the same speed (40 mph), but their velocities are different because they are traveling in opposite directions.

Answer 14

The statement "Unbalanced forces cause an object’s motion to change" is true. Unbalanced forces act on an object and cause its motion to change, either by accelerating, decelerating, or changing its direction.

Answer 15

The information necessary to calculate the winner in a boat race, in addition to the distance covered, is the time each boat takes to get to the finish line. This time measurement indicates which boat completed the distance in the shortest amount of time and determines the winner of the race.

Answer 16

Apologies for the confusion. The correct response is "The time each boat takes to get to the finish line."

Answer 17

The choice that represents velocity is "15 km/hr west." Velocity is a vector quantity that includes both speed (magnitude) and direction. In this case, the magnitude is 15 km/hr, and the direction is west.
