Explanation:
you measure temperature in degrees celsius using a thermometer. Thermal energy is measured in joules. A larger volume of water will take longer to heat up but will store more energy than the smaller object. However, a smaller object will lose it's heat faster than a larger object. A cup of tea has less thermal energy than a swimming pool.

What type of cells provide humoral immunity ?
Answers
Answer:
Antibody molecules that are secreted by plasma cells mediate the humoral immune response. The antigen that binds to the receptor of the B-cell antigen signals B cells and is internalized and transformed into peptides that activate the armed helper at the same time.
Explanation:
Answer:
B cells
Explanation:
Humoral immunity or humoural immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides. Humoral immunity is named so because it involves substances found in the humors, or body fluids. It contrasts with cell-mediated immunity. Humoral immunity is also referred to as antibody-mediated immunity.

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
Answers
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.

A 20 kg bike accelerates at 10 m/s2. What was the force? a.200 Newtons b.20 Newtons c.25 Newtons
Answers
Answer:
a.200 Newtons
Explanation:
Given the following data;
Mass = 20kg
Acceleration = 10m/s²
To find the force;
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
[tex] F = ma[/tex]
Where;
F represents force.
m represents the mass of an object.
a represents acceleration.
Substituting into the equation, we have
[tex] Force = 20 * 10 [/tex]
Force = 200 Newton.

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
Answers
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

Why do you think spacecraft that carry instruments to collect data about objects in space are called probes?
Answers
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.
