The answer is:

xA = 0

XB = 0

XC = 10.0.

The explanation:

1) From the given figure we can see that the coin B lies at the origin with coordinates (0,0).

2) and the coins A, B and C on the corners of a square.

3) The length of all sides in a square are equal. The distance between B and C form a side of a square.

4) So distance from B to C is 10 cm. Likewise, distance from B to A is also 10 cm.

5) and when B is located at point (0,0) and C is 10 units right of B, so coordinates of C will be (10,0).

6) A is located 10 units above B, so coordinates of A will be (0, 10).

7) Therefore, the x-coordinates of A, B and C are 0,0 and 10 respectively.

The X-coordinate of the coin A is $\boxed{0\,{\text{cm}}}$ , coin B is $\boxed{0\,{\text{cm}}}$ and coin C is $\boxed{10\,{\text{cm}}}$ .

Further Explanation:

The three coins A, B , C are placed in the XY plane and they are placed along the X and Y axes. The X-coordinate of the coin is the value on X-axis at which they are placed.

The coin A is placed at the $10\,{\text{cm}}$ mark on the Y- axis and if we carefully look at its position along the X axis, then it will cross the X axis at the point $x = 0\,{\text{cm}}$ . Therefore, the X-coordinate for the coin A is $\boxed{{X_A} = 0\,{\text{cm}}}$ .

Now, the coin B is placed as the intersection of the X and the Y axis. The point of intersection of the two axis in a 2-D plane is termed as the origin. It means that from this point, the plane starts. At origin the X as well as Y coordinates are zero.

Therefore, the X-coordinate for the coin is $\boxed{{X_B}=0\,{\text{cm}}}$ .

The coin is placed at a distance of 10 cm from the coin B and it is placed along the X-axis. The X-coordinate of any point along the X-axis is the distance of the point from the origin. Therefore, the X-coordinate of the coin C is $\boxed{{X_C}=10\,{\text{cm}}}$ .

Thus, the X-coordinate of the coin A is $\boxed{0\,{\text{cm}}}$ , coin B is $\boxed{0\,{\text{cm}}}$ and coin C is $\boxed{10\,{\text{cm}}}$ .

Ket [755]

Answer:

Perfectly inelastic collision

Explanation:

There are two types of collision.

1. Elastic collision : When the momentum of the system and the kinetic energy of the system is conserved, the collision is said to be elastic. For example, the collision of two atoms or molecules are considered to be elastic collision.

2. Inelastic collision: When the momentum the system is conserved but the kinetic energy is not conserved, the collision is said to be inelastic. For example, collision of a ball with the mud.

For a perfectly elastic collision, the two bodies stick together after collision.

Here, the meteorite collide with the Mars and buried inside it, the collision is said to be perfectly inelastic. here the kinetic energy of a body lost completely during the collision.

A student states that 203.9 g of table sugar will form a saturated solution in 100 g of water.

riadik2000 [5.3K]

The temperature and the solubility of sugar at that temperature

Explanation:

The amount of substance which can be dissolved in the solvent depends on the temperature.

As the temperature increases, more substance can be dissolved.

A solution is saturated if any more of the solute cannot be dissolved in the solution at the given temperature

Hence we need to know the temperature and also the amount of substance which can be dissolved(solubility) at the same temperature

a) the statement given in option A is correct

b) molar mass has no correlation with the substance's solubility and hence option b is not correct

c) The percent by volume of the solution is not needed to find if the solution is saturated and hence option c is not correct

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with acceleration of −5.2

sergejj [24]

Answer:

The car strikes the tree with a final speed of 4.165 m/s

The acceleration need to be of -5.19 m/seg2 to avoid collision by 0.5m

Explanation:

First we need to calculate the initial speed $V_{0}$

$x=V_{0} *t+\frac{1}{2} *a*(t^{2} )\\62.5m=V_{0} *4.15s+\frac{1}{2} *-5.25\frac{m}{s^{2} } *(4.15^{2} )\\V_{0}=25.953\frac{m}{s}$

Once we have the initial speed, we can isolate the final speed from following equation:

$V_{f} =V_{0} +a*t$ $V_{f}= 4.165 \frac{m}{s}$

Then we can calculate the aceleration where the car stops 0.5 m before striking the tree.

To do that, we replace 62 m in the first formula, as follows:

$x=V_{0} *t+\frac{1}{2} *a*(t^{2} )\\62m=25.953\frac{m}{s}*4.15s+\frac{1}{2} *-a\frac{m}{s^{2} } *(4.15^{2} )\\a=-5.19\frac{m}{s^{2} }$
