The answer is B.) Has mass of 1 amu

Explanation:

Neutrons have no charge so its not A or D and electrons are the things that orbit the nucleus so it not c.

Answer:

B. the object will begin to move

Explanation:

If energy is transferred the object will definitely change so it CANNOT be "A". If you add energy the object will have more force so it CANNOT be "C". The mass of an object can't increase just by giving an object energy so it CANNOT be "D"

When energy is transferred to an object, the object is most likely to move either it gains a kinetic energy or it undergo a thermal vibration if thermal energy is applied.

Energy can be transferred from its high energetic area to less . All forms of energy can be transferred like this.For example, heat energy can be transferred through various modes such as conduction, convection, radiation etc.

When an object gain some energy its particles starts to vibrate and move apart. This makes the intermolecular force of attraction between molecules weaker than before and they tend to be more reactive.

The energy transferred to an object does not make any change in mass, or any of its innate properties or does not apply any force. Therefore, option B is correct.

Explanation:

The SI unit of power is the kilogram-meter2 per second cubed, which is called the watt (1 W = 1 kg-m2/s3). Since power is the energy used per unit of time, it is derived as the energy/time quotient.

Kelvin is a fundamental unit! It's a lot easier to measure temperature than to measure the motion of component particles. Hence, we can accept it as a fundamental quantity. Time is said to be a fundamental unit because it is not dependent on one or more units

Answer:

smaller

Explanation:

Water have more evaporation

it's cause the magnetic force is greater where the field lines are crowded

since all the magnetic field lines generate from the poles, the crowd of field lines is maximum near pole

Science is the study of the natural world by collecting data through a systematic process called the scientific method. And technology is where we apply science to create devices that can solve problems and do tasks. Technology is literally the application of science

Explanation:

Answer: distance = 75ft

displacement = 35ft east

The required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.

To solve this problem, we first need to understand the difference between distance and displacement.

Distance is the total length traveled by an object, regardless of its starting and ending points. In this case, the distance traveled by Maria would be the sum of the distances of each segment of her journey,
Distance = 20 ft + 35 ft + 20 ft = 75 ft

Displacement, on the other hand, is the straight-line distance from the starting point to the ending point, measured in a straight line.

So let's assume the movement of maria on  coordinate where North and East are positive movements and West and south are negative now add the distances,

Displacement =20 + 35 - 20 = 35 ft

Thus, the required displacement of maria to get to the pool is 35 ft and the distance is 75 ft.

Explanation:

Given that,

A student covered a distance of 210 meters in 35 seconds.

We need to find the student's speed in meters/second and also in meters/minute.

Speed, v = distance (d)/time (t)

So,

[tex]v=\dfrac{210\ m}{35\ s}\\\\=6\ m/s[/tex]

We know that, 1 minute = 60 seconds

[tex]6\dfrac{m}{s}=6\times \dfrac{m}{(\dfrac{1}{60})\ \text{minutes}}\\\\=360\ \text{meters/minutes}[/tex]

Hence, the student's speed is 6 m/s or 360 meters/minute.

Answer:

The farmer should go approximately 26.39° relative to the direction of and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river

Explanation:

The given parameters are;

The river current velocity = 2.0 m/s

The boat speed relative to the water = 4.5 m/s

Therefore, for the boat to have a resultant velocity that will follow a straight path directly across the river, we have;

The water current velocity, 2 m/s, the relative speed of the boat, 4.5 m/s, and the resultant velocity, v, form a right triangle, with the water current being the base, and the boat's relative speed being the hypotenuse side, while the height is the resultant velocity

Therefore, we have;

The direction of the boat relative to the direction of current the river = θ

The relative speed of the boat × sin(θ°) = The river current velocity

∴ sin(θ°) = The river current velocity/(The relative speed of the boat)

Which gives;

sin(θ°) = 2 m/s/(4.5 m/s) = 2/4.5 = 4/9

θ = sin⁻¹ = sin⁻¹(4/9) ≈ 26.39°

Therefore, the farmer should go approximately 26.39° relative to the direction of  and toward the river current velocity or approximate 90 - 26.39 which is 63.12° clockwise from the perpendicular direction across the river.

Explanation:

Let yellow ball be m1 = 0.5kg with u1 = 8 m/s and blue ball be m2 = 0.25 kg with u2 = - 4 m /s respectively.

After collision, blue ball travels 12 m/s.

Using conservation of Linear Momentum :

m1u1 + m2u2 = m1v1 + m2v2

0.5* 8 + 0.25 * - 4 = 0.5 * v1 + 0.25 * 12

v1 = 0 m/sec i.e. Yellow ball comes to rest.

1. density = mass / volume

2. kg/mL,  g/cm³

3. volume = mass / density

4. mass = density x volume

5.  

d = m / v

d = 32.9 g / 45.78 mL

d = 0.72 g/mL

6.

vol = m / d

vol = 0.62 g / 120g/cm³

vol = 0.00517 cm³

m = v * d

m = 2.07 g/mL * 60.9 mL

m = 126.063 g

Answer:

Weight on Earth = We = 186.2 N

Weight on Mars = Wm = 70.94 N

Explanation:

The weight of an object is defined as the force applied on the object by the gravitational field. The magnitude of weight is given by the following formula:

W = mg

were,

W= Weight of Eric

m = mass of Eric

g = acceleration due to gravity

ON EARTH:

W = We = Eric's Weight on Earth = ?

m = Eric's Mass on Earth = 19 kg

ge = acceleration due to gravity on Earth = 9.8 m/s²

Therefore,

We = (19 kg)(9.8 m/s²)

We = 186.2 N

ON MARS:

W = Wm = Eric's Weight on Mars = ?

m = Eric's Mass on Mars = 19 kg

gm = acceleration due to gravity on Mars = 0.381(ge) = (0.381)9.8 m/s² = 3.733 m/s²

Therefore,

Wm = (19 kg)(3.733 m/s²)

Wm = 70.94 N

Answer:

16.77 m/s, 26.57° south of west

Explanation:

The two velocities form a right triangle.  Use Pythagorean theorem to find the magnitude of the resultant velocity.

v² = (-15 m/s)² + (-7.5 m/s)²

v = 16.77 m/s

Use trig to find the angle.

tan θ = ((-7.5 m/s) / (-15 m/s))

θ = 26.57° south of west

Answer:

Voltage is a measure of how much energy is delivered to charge. At its most basic, an electron (basic charge) is imparted 1.602×10^−19 joules when moved through an electric potential difference of one volt. An electron is then said to have an energy of 1 electronvolt. So, voltage is energy divided by charge.
