Question 19 of 20
Planets A and B have the same size, mass, and direction of travel, but planet
A is traveling through space at half the speed of planet B. Which statement
correctly explains the weight you would experience on each planet?
A. You would weigh less on planet B because it is traveling twice as
fast as planet A.
B. You would weigh the same on both planets because your mass
would adjust depending on the planet's speed.
O C. You would weigh more on planet B because it is traveling twice as
fast as planet A.
D. You would weigh the same on both planets because their masses
and the distance to their centers of gravity are the same.

Is this ok?......I have got the answer in pascals.

Answer:

Approximately [tex]10\; \rm m \cdot s^{-1}[/tex] at [tex]5.6^\circ[/tex] below the horizon.

(Assumption: air resistance on the ball is negligible; [tex]g = 9.81\; \rm m \cdot s^{-2}[/tex].)

Explanation:

Assume that the air resistance on the ball is negligible. The horizontal component of the velocity of the ball would stay the same at [tex]10\; \rm m \cdot s^{-1}[/tex] until the ball reaches the ground.

On the other hand, the vertical component of the ball would increase (downwards) at a rate of [tex]g = 9.81\; \rm m\cdot s^{-2}[/tex] (where [tex]g[/tex] is the acceleration due to gravity.) In [tex]0.1\; \rm s[/tex], the vertical component of the velocity of this ball would have increased by [tex]9.81\; \rm m \cdot s^{-2} \times 0.10\; \rm s = 0.981\; \rm m \cdot s^{-1}[/tex].

However, right after the ball rolled off the edge of the table, the vertical component of the velocity of this ball was [tex]0\; \rm m\cdot s^{-1}[/tex]. Hence, [tex]0.10\; \rm s[/tex] after the ball rolled off the table, the vertical component of the velocity of this ball would be [tex]0\; \rm m \cdot s^{-1} + 0.981\; \rm m\cdot s^{-1} = 0.981\; \rm m \cdot s^{-1}[/tex].

Calculate the magnitude of the velocity of this ball. Let [tex]v_{x}[/tex] and [tex]v_{y}[/tex] and denote the horizontal and vertical component of the velocity of this ball, respectively. The magnitude of the velocity of this ball would be [tex]\displaystyle \sqrt{{v_x}^{2} + {v_y}^{2}}[/tex].

At [tex]0.10\; \rm s[/tex] after the ball rolled off the table, [tex]v_x = 10\; \rm m \cdot s^{-1}[/tex] while [tex]v_y = 0.981\; \rm m \cdot s^{-1}[/tex]. Calculate the magnitude of the velocity of the ball at this moment:

[tex]\begin{aligned} \| v \| &= \sqrt{{v_x}^{2} + {v_y}^{2}} \\ &= \sqrt{\left(10\; \rm m \cdot s^{-1}\right)^{2} + \left(0.981\; \rm m \cdot s^{-1}\right)^{2}} \\ &\approx 10.0\; \rm m\cdot s^{-1}\end{aligned}[/tex].

Calculate the angle between the horizon and the velocity of the ball (a vector) at that moment. Let [tex]\theta[/tex] denote that angle.

[tex]\displaystyle \tan \theta = \frac{\text{rise}}{\text{run}}[/tex].

For the vector representing the velocity of this ball:

[tex]\displaystyle \tan \theta = \frac{0.981\; \rm m \cdot s^{-1}}{10\; \rm m \cdot s^{-1}} = 0.0981[/tex].

Calculate the size of this angle:

[tex]\theta = \arctan 0.0981 \approx 5.62^\circ[/tex].

Notice that the vertical component of the velocity of this ball at that moment points downwards (towards the ground.) Hence, the corresponding velocity should point below the horizon.

Answer:

you need to multiply them and then you have your answer eg = 810 × 6.7 = 5427kg

Resultant force would accelerate an 810 kg mass at 6.7 m/s² 5427 N

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Given in the question,

Acceleration (a) = 6.7 m/s²

Mass (m) = 810 kg

Force (F) = ?

We know

F = M * a

F = 810 * 6.7

F = 5427 N

Resultant force would accelerate an 810 kg mass at 6.7 m/s² 5427 N

Answer:

Percentage of mass converted to energy = 99.9 %

Explanation:

By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star. Seen from afar (on the scale of distances between stars) the presence of the solar system would not be obvious. We would simply see a normal-looking star. Perhaps we would pick up the presence of Jupiter, which makes up two thirds or so of the solar system outside of the Sun, by mass.

Answer:

1 watt is the same as the transfer of 1 joules per second.

1 watt is the same as the transfer of energy at a rate of 1 joule per second.

A watt is a unit of power, representing the amount of energy transferred or converted per unit of time. Specifically, 1 watt is equivalent to 1 joule of energy being transferred every second. It is a common metric used to measure the rate of energy flow or work done in various systems. For example, a 100-watt light bulb converts electrical energy into light and heat at a rate of 100 joules per second. Understanding power in terms of watts helps us quantify and compare the efficiency and performance of different devices and processes.

weight on earth is mg

which is 5*9.8

49 Newton

weight on moon is 1/6 th of weight on earth

1/6*49

8.166 Newton..

Answer:

1

For instance, on Earth, a 5.0-kg object weighs 49 N; on the Moon, where g is 1.67 m/s2, the object weighs 8.4 N.

2

The weight of the object on the surface of earth would be 5kg. The weight of the object on the surface of moon would be 5/6= 0.83 as the weight of any object on earth is six times than that on moon.

Explanation:

Can read mass precisely, commonly reading error of +0.05g

Mass is a measure of the amount of matter in a substance.  Mass can be measured using a triple beam balance. Hence option (A) is correct.

In physics, mass is a quantitative measurement of inertia, a basic characteristic of all matter. It essentially refers to a body of matter's resistance to changing its speed or location in response to the application of a force. The change caused by an applied force is smaller the more mass a body has. The kilograms serves as the unit of mass in the International System of Units (SI).

The conservation of mass principle states that no matter how an object's component pieces are rearranged, the object's overall mass remains constant. If a body splits into parts, the mass also splits into pieces, therefore the original mass is equal to the sum of the masses of the individual fragments. Alternatively, if two or more particles are combined, the mass of the resulting composite equals the total of the masses of the individual particles. This rule is not always accurate, though.
