Answer:
Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

Juan rides his horse with a constant
speed of 18 km/h. How far can he travel
in 1/2 hour?
Answer:
He traveled 9km
Explanation:
To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km

How does the sun maintain its high temperature and energy output?
Answer:
The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). ... The core is the only part of the sun that produces an appreciable amount of heat through fusion.
Explanation:
I got you
By not running out of fuel (Hydrogen).
Rest assured ... When the sun runs low on Hydrogen, it'll go through several complex changes, and it'll end up at much much lower temperature, with much much lower energy output.
If an engine can produce 670 J of energy in 1 min, how many watts can it output?
Answer:
11.2Watts
Explanation:
Given parameters:
Energy produced by the engine = 670J
Time taken = 1min = 60s
Unknown:
Number of watts it can output = ?
Solution:
This problem entails finding the power of the engine.
Power is the rate at which work is being done.
So;
Power = [tex]\frac{Work done }{time}[/tex]
Power = [tex]\frac{670}{60}[/tex] = 11.2Watts

Answer:
C. 2 and 4
Explanation:
my teacher went over it and the answer was that
The sections of the track in which the sled would experience an unbalanced force are: C. Sections 2 and 4.
The two types of force.In Science, there are two (2) main types of force that acts on an object and these include:
Balanced forceUnbalanced forceWhat is an unbalanced force?An unbalanced force refers to a type of force that occurs when two (2) or more forces acting on an object are unequal in magnitude, and as such, it typically results in a change of motion.
In this scenario, the sections of the track in which the sled would experience an unbalanced force are sections 2 and 4 respectively.

A bag weighing 20 N is pushed horizontally a distance of 35 m across a
level floor by a force of 10 N, How much work is done on the bag in
Joules? W=Fd *
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J

Is a violin and battery potential energy?
Explanation:
In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The battery is storing the energy but give it something to power and it'll give its energy to the object and a violin strings are like ruber band and if you play the violin it releases a new type of energy sound energy.

A 250 kg car has 6875 kg•m/s of momentum. What is it’s velocity?
Answer:
v = 27.5 m/s
Explanation:
p = m × v
6,875 = 250 × v
250v = 6,875
v = 6,875/250
v = 27.5 m/s
Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator. tafu models its position with the function p(t)= t2 t â 1 where t>1. in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. (a) calculate the limit
Answer:
Infinity
Explanation:
When you have a limit approaching infinity one method you can use is to remember that the highest power dominants all of the other ones so when we have (t^2)/t-1 like in your problem, we see that t^2 has the highest power of 2 so if that's going to infinity and it's not being divided by any powers higher than it will just be inifinity.
We have that for the Question, it can be said that in the limit calculations below, if you need to use -â or â, enter -infinity or infinity. the limit is
[tex]Lim_{t->\infty} p(t)= \infty[/tex]
From the question we are told
Tafu is working with subatomic particles in the physics lab. a positron is traveling in a straight line down the particle accelerator.tafu models its position with the function
p(t)= t2 t â 1 where t>1.
in the limit calculations below, if you need to use -â or â, enter -infinity or infinity.
(a) calculate the limit
Generally the equation for the Question is mathematically given as
[tex]p(t)=\frac{t^2}{t-1}\\\\Therefore\\\\For Lim_{\infty}\\\\We have\\\\ Lim_{t->\infty} p(t)= Lim_{t->\infty}\frac{t^2}{t-1}\\\\[/tex]
Since, the equivalent degree of numerator (t^2) is greater than that of the denominator
[tex]Lim_{t->\infty} p(t)= \infty[/tex]

What is the unit of a force, and what is 1 unit equivalent to?
Answer:
Newton
Explanation:
The unit of force is Newton and it is given after Sir Isaac Newton for his tremendous works in this regard.
Force is the product of mass and acceleration of a body.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
So;
1N = 1kgm/s²
Therefore, the unit of force is newtons and 1N is equal to 1kgm/s²
A wave with a frequency of 28 Hz has a wavelength of 6 meters. At what speed will this wave travel?
Answer:
168m/s
Explanation:
Given parameters:
Frequency = 28Hz

Answer:
D
Explanation:
The density has a formula of d = m / V.
The volumes are given as the same.
The density will be
d_lead = 113/ V
d_aluminum = 27/V
It does not matter for this question what the volume actually is. Just note that the value of the volume is the same for each ball.
A: incorrect. If the volumes are the same, the density is not the same because the masses are different.
B: incorrect. If the density of the two balls was less than water, the two balls would float. Never going to happen unless the balls are thin shells.
C: incorrect. The exact opposite is the answer.
D: Correct. This is the answer.
