Answer:

momentum

Explanation:

The net impulse delivered to an object always causes a change in the object's momentum. Hence, option (B) is correct.

The given problem is based on the concept of net impulse. The magnitude of force acting on any object for very short interval of time is known as impulse. In the given problem, the transfer of impulse can be explained by the impulse - momentum theorem.

[tex]F \times t = \Delta P\\\\I= \Delta P[/tex]

Here, I is the impulse.

Thus, we can conclude that the net impulse delivered to an object always causes a change in the object's momentum. Hence, option (B) is correct.

Answer:

for part 1 the answer is 0.303

Explanation:

Given that,

Mass of a frog, m = 0.5 kg

The frog leaps pushing off of the rock with an acceleration of 5.0 m/s².

To find,

The magnitude of the net force exerted on the frog as it leaps.

Solution,

Let the net force exerted on the frog is given by the formula as follows :

F = ma

Putting the values of m and a to find F as follows :

F = 0.5 kg × 5 m/s²

F = 2.5 N

So, the magnitude of net force is 2.5 N.

The magnitude of the net force exerted on the frog as it leaps is 2.5 Newtons.

Hence, Option a) 2.5N is the correct answer.

Given the data in the question;

Force Exerted; [tex]F = ?[/tex]

To determine the magnitude of the net force exerted on the frog as it leaps, we the expression from the Newton's Second law of motion:

[tex]F = m * a[/tex]

Where m is mass and a is acceleration

We substitute our given values into the equation

[tex]F = 0.5kg * 5.0m/s^2\\\\F = 2.5kgm/s^2\\\\F= 2.5N[/tex]

The magnitude of the net force exerted on the frog as it leaps is 2.5 Newtons.

Hence, Option a) 2.5N is the correct answer.

Answer:

D is the correct answer

Explanation:

A) shows low accuracy and high precision since they missed the bull's-eye but are all grouped together.      

B) Shows high accuracy and high precision

C) Shows high precision

D  is the only one that shows both low accuracy and low precision

The illustration represents low accuracy and low precision is according to option D.

When in an experiment, a value is measured 5 times, then if the values measured are same for most of the time or like three times out of five, it said to be accurate. The phenomenon is accuracy.

Precision is about comparing the values to each other then find them near to each other.

Accuracy compares the experimental value to the theoretical value.

So, when all the values are close to each other but not nearest to the theoretical value, then it is said to be precise but not accurate.

Thus, the correct option for low accuracy and precision is D.

Answer:

The value is  [tex]t = 18.6 s[/tex]

Explanation:

From the question we are told that

     The average acceleration of the bicycle is [tex]v = -0.44 \ m/s^2[/tex]

      The initial forward velocity is  [tex]u = 8.2 \ m/s[/tex]

Generally from kinematic equations we have that

      [tex]v = u + at[/tex]

Here v is the final velocity of the bicycle and the value is v = 0 m/s

So

      [tex]0 = 8.2 + (-0.44)t[/tex]

=>    t = 18.6 s

12.00 min = 0.2 hr

8.00 min = 0.15 hr

Total distance:

(10.0 km/hr) (0.2 hr) + (15.0 km/hr) (0.15 hr) + (20.0 km/hr) (0.2 hr)

= 8.25 km

Average speed:

(10.0 km/hr + 15.0 km/hr + 20.0 km/hr) / 3

= 15 km/hr

Change in position:

(10.0 km/hr) (0.2 hr) + (15.0 km/hr) (0.15 hr) - (20.0 km/hr) (0.2 hr)

= 0.25 km

Average velocity:

Answer:

D :)

Explanation:

When an impact causes the car to suddenly change its motion, (D) the people in the car will continue to move in the same direction and at the same speed as before the impact.

Newton's first law of motion states that Unless influenced by an imbalanced force, a body at rest stays at rest, and a body in motion keeps moving in a straight path at a constant pace. This law is commonly known as law of inertia and the resistance of a body to maintain its state of rest is called inertia of rest, same as, the resistance of a body to maintain its state of motion is called inertia of motion.

When a car is moving with certain speed, the car along with the people inside the car is in inertia of motion. In an event of accident, the car comes in rest in no time but the man in the car is still in inertia of motion. So, his body moves forward in the car which may cause injuries. To prevent such injuries, the people inside a car are advised to use safety belts.

So, correct answer  is option (D).

#SPJ2

Answer:

Newton's law of gravitation states that every object in this universe attracts every other object with a force called gravity,

when the distance between the two object is increased the gravitational force decreases by its square,

and when the mass an object increases the gravitational force also increases,

therefore, gravitational force is directly proportional to the mass of the two objects and is square inversely proportional to distance between them.

Answer:

40 N

Explanation:

We first need to calculate the acceleration of the tron ball.

Since acceleration, a = (v - u)/t where u = initial velocity of iron ball = 17m/s, v = final velocity of iron ball = 27m/s and t = time taken for the change in velocity = 5 s.

So, a = (v - u)/t

= (27 m/s - 17 m/s)/5 s

= 10 m/s ÷ 5 s

= 2 m/s²

We know force on iron ball, F = ma where m = mass of iron ball = 20 kg and a = acceleration = 2 m/s²

So, F = ma

= 20 kg × 2 m/s²

= 40 kgm/s²

= 40 N

So, the magnitude of the force on the iron ball is 40 N.
