Sachi wants to throw a water balloon to knock over a target and win a prize. The target will only fall over if it is hit with a force of 0. 035 N. The water balloon has a mass of 11. 4 grams. How fast will Sachi have to make the water balloon accelerate to hit the target with enough force and win the prize? Round the answer to the nearest one tenth m/s2. The water balloon must accelerate m/s2.

Answer:

[tex]\boxed {\boxed {\sf A. \ 2 \ m/s}}[/tex]

Explanation:

Speed is the distance traveled per unit of time, or how fast an object is moving.

It is calculated by dividing the distance by the time.

[tex]s= \frac{d}{t}[/tex]

Jake traveled 10 meters in 5 seconds.

Substitute the values into the formula.

[tex]s= \frac{10 \ m}{5 \ s}[/tex]

Divide.

[tex]s= 2 \ m/s[/tex]

Jake's speed was 2 meters per second and choice A is correct.

Answer:

c. postive

Explanation:

All physical objects are made up of atoms. Inside an atom are protons, electrons and neutrons. The protons are positively charged, the electrons are negatively charged, and the neutrons are neutral.

Therefore, all things are made up of charges. Opposite charges attract each other (negative to positive). Like charges repel each other (positive to positive or negative to negative). Most of the time positive and negative charges are balanced in an object, which makes that object neutral.

Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit.

Answer:

C

Explanation:

C because if you build anything up it remains the same.

y = y 0 + v 0 y t − 1 2 g t 2 . If we take the initial position y 0 to be zero, then the final position is y = 10 m. The initial vertical velocity is the vertical component of the initial velocity: v 0 y = v 0 sin θ 0 = ( 30.0 m / s ) sin 45 ° = 21.2 m / s .

Explanation:

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]k = \frac{1}{2} m {v}^{2} \\ [/tex]

m is the mass in kg

v is the velocity of the object in m/s

From the question

m = 100 kg

v = 10 m/s

We have

[tex]k = \frac{1}{2} \times 100 \times {10}^{2} \\ = 50 \times 100 \\ = 5000 \: \: \: \: \: \: \: \: [/tex]

Answer:

represents the energy the object possesses by virtue of its motion. ... This type of energy is generally known as kinetic energy. Thus, Equation (16) states that any work done on point object by an external force goes to increase the object's kinetic energy.

Explanation:

   The relation between some bodies are involved by Object's position and motion, i.e., through potential and kinetic energy in which it actually explained by Newton's second law of motion.

Definition:

      Newton's second law states that force is equal to the rate of change of momentum, i.e., the mass and velocity.

Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They're also called longitudinal waves because the air vibrates along the same direction as the wave travels.

The characteristics of the universal gravitation law allow finding the results for which statements are true:

    2. Real stars must be at least 2 to 3 times more massive than our sun to become a black hole.

The universal gravitational law states that the gravitational force is always attractive and is proportional to the masses and inversely proportional to the square of the distance.

       [tex]F = - G \frac{Mm}{r^2}[/tex]

Where F is the force, G is the universal gravitational constant, M and m are the masses and r the distance between the bodies.

Let's analyze the expressions:

1. The gravitational field around a planet is oriented radically outward

False. The force is attractive therefore it is directed towards the center of the planet.

2. Real stars must be at least 2 to 3 times more massive than our sun to become a black hole.

True. From observations of super-novae the minimum mass is 3 solar masses.

3. Astronauts in orbit are weightless due to the absence of a supporting force.

False. Astronauts have no weight because the force of gravity binds to change the direction of their velocity.

4. The outer planets of our solar system wobble in their orbits because the gravitational effects of the sun are very small.

False. The attraction of the sun decreases with the square of the distance, but the wobble is due to the attraction of the other large planets in this area.

5. The earth falls towards the sun.

False. The earth has a speed parallel to the orbit around the sun and the acceleration due to the attraction of the sun changes the direction of the orbital velocity, but the earth is not directed at the sun.

6, As you move away from the ground, the gravitational force acting on you increases.

False. The gravitational force is inversely proportional to the distance, therefore it decreases when leaving the earth.

In conclusion with the characteristics of the universal gravitation law we can find which statements are true:

     2. Real stars must be at least 2 to 3 times more massive than our sun to become a black hole.

Answer: Coral reef structures also buffer shorelines against 97 percent of the energy from waves, storms, and floods, helping to prevent loss of life, property damage, and erosion. When reefs are damaged or destroyed, the absence of this natural barrier can increase the damage to coastal communities from normal wave action and violent storms.

Answer:

2 m/s2

Explanation:

|acceleration| = (change in speed) divided by (time for the change)

Change in speed = (end speed) minus (start speed)

Initial speed of walking = 1 m/s

Final speed of walking = 3 m/s

Change of speed in walking = (3 - 1) m/s

                                            = 2 m/s

Time in which the change of speed occurred = 1 sec

Then

Acceleration = Change of Speed/ Time taken

                    = 2/1 m/s^2

                    = 2 m/s^2

Therefore the answer is 2 m/s2.

The acceleration is 2 m/s².

Acceleration can be defined as the rate of change of velocity.

Answer:

We don't know how much it cost bc u didn't give us a number of how much one person cost or any details but if you add both of the balls together they have 1,400 balls

To calculate the cost of paintballing for Ryan and his dad, we need to know the cost per paintball. Once we have that information, we can multiply it by the total number of paintballs they used (700 balls each).

Let's say the cost per paintball is $0.50.

For Ryan:

Cost for Ryan = Cost per paintball × Number of paintballs used by Ryan

Cost for Ryan = $0.50/ball × 700 balls = $350

For his dad:

Cost for Dad = Cost per paintball × Number of paintballs used by Dad

Cost for Dad = $0.50/ball × 700 balls = $350

Total cost for both of them:

Total Cost = Cost for Ryan + Cost for Dad

Total Cost = $350 + $350 = $700

So, the total cost of paintballing for Ryan and his dad is $700, assuming the cost per paintball is $0.50.
