A car and a delivery truck both start from rest and travel at the same rate, 5 m/sec. The truck travels for 5 seconds, while the car travels for 10 seconds. What is the traveled distance of the car compared to the truck? * a. Half as much b. The same c. Twice as much d. Four times as much

Answers

Answer 1

Answer:

c. Twice as much

Explanation:

The distance covered by the truck and the truck can be found by the following equation:

[tex]s = vt[/tex]

where,

s = distance covered

v = speed

t = time

FOR CAR:

[tex]s_{car} = (5\ m/s)(10 s)\\s_{car} = 50\ m[/tex]

FOR TRUCK:

[tex]s_{truck} = (5\ m/s)(5 s)\\s_{struck} = 25\ m[/tex]

Therefore,

[tex]\frac{s_{car}}{s_{truck}} = \frac{50\ m}{25\ m} \\s_{car} = 2s_{truck}[/tex]

The distance covered by the car is twice as much as the distance covered by the truck. So, he correct answer is:

c. Twice as much

How much does a 20 kg rock weigh on Earth where g = 9.8 m/s2?

Answers

Answer:

[tex]\huge\boxed{196\:N}[/tex]

Explanation:

Mass and weight ain't the same thing. So, for calculating weight we would use Newton's 2nd Law of Motion i.e. Force = Mass × Acceleration.

According to question,

The mass is 20kg

Acceleration is 9.8 m/s^2

Putting the given values into the formula,

F = 20 × 9.8

F = 196N

So, the weight of the rock is 196 N

Answers

Answer:

The inner, rocky planets are smaller than the outer, gaseous planets

Explanation:

The relationship between the sizes of the planets and their distances from the Sun is: The smaller planets are closer to the sun while the bigger planets are farther from the sun.

A solar system can be defined as a collection of both the inner and outer planetary bodies alongside the Moon in orbit (travel) around the Sun, in slightly elliptical orbits.  

Basically, the nine (9) planets of the solar system orbiting (traveling) in order of their distance around the Sun are;

Mercury.Venus.Earth.Mars.Jupiter.Uranus.Neptune.Pluto.Venus.Saturn.

Basically, the relationship between the sizes of the planets and their distances from the Sun is that the smaller planets are closer to the sun while the bigger planets are farther from the sun.

When you walk across the ground and push on it with your feet...
Group of answer choices

The ground pushes back more strongly than your feet

The ground pushes back on your feet with equal force

There is no effect on the ground

The ground pushes back less strongly than your feet

Answers

Answer:

The ground pushes back on your feet with equal force

Explanation:

When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.

This interpretation and knowledge is gotten from Newton's third law of motion.

It states that "action and reaction force are equal and opposite in nature".

The force applied to a body responds with an opposite force in the other direction. Therefore, the reaction force is of equal magnitude but directed in another direction.

Answer:

the answer is the second one: the ground pushes back on your feet with equal force

A student buys a plastic dart gun and tries to find the maximum horizontal range. The student shoots the gun straight up and it takes 3.7 seconds for the dart to return back to the height of the barrel. What is the maximum horizontal range of the gun?

Answers

Answer:

The value is [tex]R_{max} = 33.54 \ m[/tex]

Explanation:

From the question we are told that

    The total time of flight is  [tex]t = 3.7 \ s[/tex]

Generally from kinematic equation

        [tex]v = u - g * \frac{t}{2}[/tex]

So v is the velocity at maximum height and the value is  v = 0 m/s

So

       [tex]0 = u - 9.8 * \frac{ 3.7}{2}[/tex]

=>   [tex]u = 18.13 \ m/s[/tex]

Here u  is the initial velocity of the dart as it leaves that gun  

Gnerally the horizontal range of the dart is mathematically represented as

         [tex]R = \frac{u ^2 sin 2\theta }{g}[/tex]

For maximum horizontal range the value of  [tex]\theta = 45^o[/tex]        

So

         [tex]R_{max} = \frac{ 18.13 ^2 sin 2(45) }{9.8}[/tex]

=>     [tex]R_{max} = 33.54 \ m[/tex]

An object has an x-momentum of 8.5 kilogram-meters/second and a -momentum of 9.8 kilogram meters/second. What Is resultänt
momentum of the object?
OA 15.5 kilogram-meters/second
OB. 14.8 kilogram-meters/second
0c 12.97 kilogram-meters/second
OD. 16.8 kilogram-meters/second

Answers

Answer:

The resultant momentum is 12.97 kg.m/s. Choice: c

Explanation:

Momentum

The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".

As a vector, it can be expressed by its rectangular components:

[tex]\vec p = p_x\mathbf{i}+p_y\mathbf{j}[/tex]

The magnitude of the momentum is:

[tex]\mid \mid \vec p \mid \mid =\sqrt{p_x^2+p_y^2}[/tex]

The object described has an x-component of:

px=8.5 Kg.m/s

And a y-component of:

py=9.8 Kg.m/s

Thus, the magnitude of the momentum is:

[tex]\mid \mid \vec p \mid \mid =\sqrt{8.5^2+9.8^2}[/tex]

[tex]\mid \mid \vec p \mid \mid =\sqrt{72.25+96.04}[/tex]

[tex]\mid \mid \vec p \mid \mid =\sqrt{168.29}[/tex]

[tex]\mid \mid \vec p \mid \mid =12.97[/tex]

The resultant momentum is 12.97 kg.m/s. Choice: c

Form hypothesis: How do you think increasing the resistance in a circuit will affect the current in the wire? (format: if, then, because)

Answers

Answer:it would make it thicker

Explanation:

Answer:

"The equation shows that the current in a circuit is inversely proportional to the resistance of the circuit. An increase in resistance would result in a decrease in current. And the factor by which the resistance increases is the same factor by which the current decreases."

Explanation:

Because it's just like wearing a glove/mitten when getting something out of the oven, because of the insulation from the glove/mitten, it reduces the heat that gets through into your hand, and it protects it. Just like what the "answer" says, it said that the resistance would decrease current.
