Jack bought 8 boxes of soda. how many cans did he buy if each box holds 34 cans?

Answer:

mechanical energy

Explanation:

The key difference that exists between kinetic energy and potential energy lies in the fact that, potential energy is that form of mechanical energy which is stored within an object, ready to be released as and when needed to do some work, while, kinetic energy is that form of mechanical energy that has been released and is associated with the body in motion.

Answer:

Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth

Explanation:

Answer:

No

Explanation:

becuse it's not even outer space there's acceleration there's no such thing as Zero acceleration speed except if you're not in motion.

Answer:

50 mph

Answer:

C

Explanation:

I'm not 200% sure whether net acceleration would be F1 - F2 or F1 + F2, but C works in both scenarios. Either the net acceleration is 18 N, which is the lowest, or it is 8 N, which is also the lowest.

Answer:

Tech B

Explanation:

The control of electric actuators may be through through a two-wire or a five-wire circuit through the driver circuit by bidirectionally controlling via the motor wire polarity. The door position is determined by counting the actuator commutator pulses by the control module in the actuator with 2-wire, while the actuator with 5-wire uses potentiometer feedback.

The A/C ECU is the Air Condition Engine Control Unit.

Explanation:

Answer:

[tex]F_{g} = \frac{m}{d^{2} }[/tex] shows the relationship between gravity and mass.

Explanation:

According to the Newton's law of gravitation, the gravitational force between two bodies is,

       [tex]F_{g} = G.\frac{m_{1}.m_{2} }{d^{2} }[/tex]

here [tex]m_{1} and m_{2}[/tex] are masses, d is distance between them.

It states that gravitational force acting two bodies is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

In above formula ,

If [tex]m_{1} = 1 and[/tex]  [tex]m_{2} = m[/tex]

so [tex]F_{g} = G \frac{m}{d^{2} }[/tex]

Since G is constant ,

    [tex]F_{g}[/tex] ∝[tex]\frac{m}{d^{2} }[/tex]

Hence second option is correctly showing relationship between gravity and mass.

Tola (South Asia) 2.6666675 85.73535

Answer:

Explanation:

It's a good thing to claim this was speed and not velocity.

Givens

d = 40 meters

t = 5 seconds

V = ??

Formula

v = d/t

Solution

v = 40 m/5 sec

v = 8 m/s

If you really wanted to get picky, you should convert the distance to yards which is how distance is measured in football

1.09 yards = 1 meter

d = 40 * 1.09 = 43.74 yards.

t = 5 seconds

v = 43.74/5 = 8.749 yards / second.

Explanation:

It is given that,

Initial speed of a golfer, u = 29 m/s

If it travels the maximum possible distance before landing. It means that it is projected at an angle of 45 degrees.

(a) We need to find the time spent by the ball in the air. It can be calculated by using second equation of motion.

[tex]s=ut+\dfrac{1}{2}at^2[/tex]

Here,

a = -g

s = 0 (it is displacement and it is equal to 0 as the ball lands on the green).

So,

[tex]0=29\sin(45)t-\dfrac{1}{2}\times 9.8t^2\ (\text{Initial vertical component of velocity is taken})\\\\-4.9t^2+29\times \dfrac{1}{\sqrt2}t=0\\\\-4.9t^2+20.5t=0\\\\t=0,4.184\ s[/tex]

So, it will take 4.184 seconds in the air.

(b) let x is the longest hole in one that the golfer can make if the ball does not roll when it hits the green. It can be given by :

[tex]x=vt\cos\theta\\\\x=29\times 4.184\times \cos(45)\\\\x=85.79\ m[/tex]

Hence, this is the required solution.

Answer:

Initial velocity is independent of the slope of the graph; that is, the acceleration. An object thrown downward still accelerates after release at the same rate as an object that is dropped.

2nd – Slide the large weight to the right until the arm drops below the line and then move it back one notch.

3rd – Repeat this process with the top weight. When the arm moves below the line, back it up one groove.

4th – Slide the small weight on the front beam until the lines match up.

5th – Add the amounts on each beam to find the total mass to the nearest tenth of a gram.

Explanation:

The triple beam balance is an instrument that is used in measuring the mass of substances to a very high degree of precision. The reading error is given by ±0.05 grams. The triple beam balance as the name implies has three beams that measure substances of different mass levels.

The beams are categorized as small, medium, and large. There is a balance on which the substance to be weighed is placed directly upon. To use this measuring device, the procedures mentioned above are followed.

Answer:

call for help and check if the person has not passed out (check their pulse.)

Explanation:

Answer:

Explanation

Give the initial velocity of am object as v =(4m/s)xi+(3m/s)yj

From the expression;

Vy = 3m/s

Vx = 4m/s

At the maximum height, the velocity of the body is zero i.e Vy = 0m/s

The velocity of the projectile as it reaches its highest point will be:

v = (4m/s)xi + 0

v = √4²+0²

v = √16

v = 4m/s

Hence he velocity of the projectile when it reaches its highest point is 4m/s

Surface waves are winds blowing through the  surface of ocean water. Therefore, option B is correct. All other options are just examples of waves and not wind.

Ocean water flows in currents, much like air does in the atmosphere. A current is an oceanic current, or stream, of flowing water. The primary cause of surface currents is wind, although not daily winds.

The main wind belts are what produce surface currents. These winds always blow in the same direction. so that they can maintain the direction of the water's flow.

Three factors influence surface currents: global wind patterns, Earth's rotation, and the configuration of ocean basins. Because they disperse heat over the earth, surface currents are crucial. Global climate is significantly influenced by surface currents as well.

Answer:

x = 121.86 m

Explanation:

It is given that,

The vertical velocity of a plane, [tex]v_x=18\ m/s[/tex]

It is flying above the target, h = 225 m

First we will find the time taken by the plane to reach the ground. It can be calculated using the second equation of motion as follow :

[tex]h=ut+\dfrac{1}{2}at^2[/tex]

Here, u = 0 and a = g

[tex]h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\times 225}{9.81}} \\\\t=6.77\ s[/tex]

Let x is the horizontal distance from the target. It can be calculated as follows :

[tex]x=v_xt\\\\x=18\times 6.77\\\\x=121.86\ m[/tex]

So, the rescue pilot drop the package at a distance of 121.86 m from the target.

Answer:

Acceleration is a vector, is measured in m/s, and A.

Explanation: SO BASICALLY, the answer to this question is A, B, and C. The last one would not fit the description of acceleration because it is describing Velocity.

Answer:

We have a mass of 200g (0.2kg) moving at 20m/s

Kinetic Energy KE = ½ mv^2 where m is mass and v is velocity

Actually, v is a vector quantity, so KE = ½ mv•v

The dot product of 2 vectors a and b is abCosθ where θ is the angle between the vectors.

Obviously v•v = v^2 Cos0 = v^2

In this case, we have KE = ½ (0.2)(20^2) = 40kg-m^2/s^2 = 40J

So we have kinetic energy in the amount of 40 Joules.

Explanation:

The right answer is "2.7 J"

Answer explanation:

Remember to convert grams to kilograms first by dividing by 1000.

Kinetic energy

= 1/2 × mass × speed2

= 1/2 × 0.2 kg × (5.2 m/s)^2

= 2.7 J (to 2 sig. fig.)
