Why do you think spacecraft that carry instruments to collect data about objects in space are called probes?
Answer:
my mind cant comprehend a shing word u just said
Explanation:
The probes collect data, they capture the movement in space, therefore, spacecraft that carry instruments to collect data about objects in space are called probes, So the given statement is correct.
What are Probes?
Any conductor that is placed into a plasma and gathers current is a probe. Measurements of the current on the probe as a function of the bias potential given to the probe can be used to identify a plasma's properties.
Such probes affect their surroundings while directly detecting electron and ion flows in the plasma. Any conductive material (wire, foil, chamber walls, etc.) can serve as a plasma probe; nevertheless, precise control over the probe's size, shape, and substance is necessary to achieve detectable plasma levels. Astronauts are not present aboard probes. Scientists can analyze the data the probes relay back to Earth. Sputnik 1 was the first spacecraft to launch.
Because probes probably collect data, they capture the movement in space, therefore, spacecraft that carry instruments to collect data about objects in space are called probes.

How could you explain that two objects of the same volume have different buoyancy in water???
HELP ITS URGENT
Answer:
Explanation:
Take for example you place two eggs in the water. One starts to sink and one remains floating. They have the same volume but the one that sinks is cracked just a little, which as soon as it hits the water, water starts to go in the egg. Then that changes the volume of the egg. (I've done this expirement before) It can also be the way you place the object in the water, or one object has been in the water longer. The buoyancy can be the way they are positioned/placed in the water. One may be more absorbant to the water as well.

Explanation:
A layer of water Δx m thick which lies x m above the bottom of the tank will be rectangular with length 8 m. Using similar triangles, we can see that it will have widt of_____m
Answer:
x
Explanation:
The question relates to the energy required to pump water out of the
spout at the top of the triangular prism tank.
The width of the layer of water Δx thick is x m.
Reasons:
The location of the layer Δx m thick = x meters above the bottom
The length of the triangular (cross-section) prism tank = 8 meters
The length of the layer Δx thick layer = 8 meters
From the attached drawing of the cross-section of the tank, we have;
The height of the triangular tank cross-section = 3 meters
The length of the base of the triangular cross-section = 3 meters
By similar triangles, we have;
[tex]\dfrac{Height \ of \ Tank}{Base \ length \ of \ tank}= \dfrac{Height \ of \ layer \ with \ thickness \ \Delta x }{Width \ of \ layer \ with \ thickness \ \Delta x}[/tex]
Which gives;
[tex]\dfrac{3}{3} =\dfrac{x}{Required \ width}[/tex]
[tex]\dfrac{3}{3} =1 = \dfrac{x}{Required \ width}[/tex]
Required width × 1 = x
The required width = x m

A force of 6.0 N is applied horizontally to a 3.0 kg crate initially at rest on a horizontal frictionless surface. After the crate is pushed for 1.5 seconds, it has a velocity of 3.0 m/s. Does this support Newton's second law of motion, that force equals mass times acceleration? Explain. 
a. Yes, because the acceleration of the crate is 2.0 m/s².
b. No, because the acceleration of the crate is 2.0 m/s².
c. Yes, because the mass and the velocity of the crate are equal.
d. No, because the mass and the velocity of the crate are equal.
Answer:
a. Yes, because the acceleration of the crate is 2.0 m/s².
Explanation:
Given
[tex]Force = 6N[/tex] --- f
[tex]Mass = 3kg[/tex] --- m
[tex]Time = 1.5s[/tex] --- t
[tex]Velocity = 3.0m/s[/tex] --- v
Required
Does the system support [tex]F=ma[/tex]
Yes, it does and this is shown below
The crate is initially at rest; so:
[tex]u = 0[/tex]
Using the first equation of motion
[tex]v = u + at[/tex]
Substitute values for v, u and t
[tex]3 = 0 + a*1.5[/tex]
[tex]3 = 1.5a[/tex]
Make a the subject
[tex]a = 3/1.5[/tex]
[tex]a = 2[/tex]
Using [tex]F = ma[/tex]
Substitute values for F and m
[tex]6 = 3 * a[/tex]
Divide both sides by 3
[tex]6/3 = 3/3 * a[/tex]
[tex]2 = a[/tex]
[tex]a = 2[/tex]
In both cases:

Calculate the resistance of an electric blanket that draws 9 A to transform 50 W of energy.
Answer:
The resistance is 0.617Ω.
Explanation:
Given that the formulas are V = I × R and P = I × V so when you substitute the V formula into P formula, you will get P = I² × R. Using this formula, you can find the resistance :
P = I² × R
50 = 9² × R
50 = 81 R
50 ÷ 81 = R
R = 0.617Ω (3sf)

Dl
Answer:
11.1s
Explanation:
Given parameters:
Height of cliff = 600m
Unknown:
How long it takes to hit the ground = ?
Solution:
To solve this problem, we use one of the kinematics equation;
H = ut + [tex]\frac{1}{2}[/tex]gt²
H is the height
u is the initial velocity = 0m/s
t is the time taken
g is the acceleration due to gravity
600 = [tex]\frac{1}{2}[/tex] x 9.8 x t²
600 = 4.9t²
t² = 122.5
t = 11.1s

Which situations will NOT increase the reactions rate of most chemical reactions?
A) an increase in temperature
B) grind up the solute to increase surface area before mixing
C) by increasing the pressure in which the reaction takes place
D) decreasing the concentrations of the substances in the reaction
Answer:
D
Explanation:
Increasing temperature or pressure some times make the condition favorable to the reaction. Similarly increasing surface area of reacting mixture also helps to increase the reaction rate.
What is reaction rate ?The rate of a reaction is the rate of decrease in concentration of reactant or the rate of increase in concentration of the products. The rate of a reaction depends on several factors such as temperature, pressure, surface area etc.
Fir an endothermic reaction, as the temperature increases, reaction rate increases. Similarly, as the pressure increases, the reaction in which the number of moles of gaseous reactants is higher than that in products, rate increases.
The concentration of reactants must be sufficient for the reaction and decreasing the concentration of reactants does not favor an increase in reaction rate. Hence, option D is correct.

L(/kg) c (J/(kg*C))

(Unit = J)
Answer:
33333.35 kg
Explanation:
I got it right on Acellus, rounded to 33300 sigfigs
When 0.0135 kg of steam at 100°C is cooled, turns it into water at 50.0°C. Then 33,342.45 J of heat has been removed.
What is latent heat?Latent heat is the heat absorbed or released by a substance during a change in its physical state without a corresponding change in temperature. This means that the heat energy is being used to break or form intermolecular bonds between the particles in the substance, rather than raising or lowering the temperature. Examples of processes that involve latent heat include melting, freezing, vaporization, and condensation. The amount of heat required or released during these phase transitions is dependent on the substance and the amount of material undergoing the change.
Here in the question,
To solve this problem, we need to use the formula for the heat required to change the phase of a substance, which is given by:
Q = m * L
where Q is the heat required, m is the mass of the substance, and L is the specific latent heat of the substance.
In this case, we need to find the heat required to change 0.0135 kg of steam at 100°C to water at 100°C, and then cool it down to 50°C.
First, we need to find the heat required to change the phase of the steam to water at 100°C. Using the table given, we can see that the specific latent heat of vaporization for water is 2.26 × 10^6 J/kg. So the heat required to change 0.0135 kg of steam to water at 100°C is:
Q1 = m * L = 0.0135 kg * 2.26 × 10^6 J/kg = 30,510 J
Next, we need to find the heat required to cool the water from 100°C to 50°C. Using the specific heat capacity of water, which is 4186 J/(kg°C), we can calculate the heat required as:
Q2 = m * c * ΔT = 0.0135 kg * 4186 J/(kg°C) * (100°C - 50°C) = 2832.45 J
The total heat removed is the sum of the heat required to change the phase of the steam and the heat required to cool the water:
Q = Q1 + Q2 = 30,510 J + 2832.45 J = 33,342.45 J =33.34245 kJ.
Therefore, 33,342.45 J of heat has been removed.
