The acceleration that the same force will provide if both masses are tied together is; 6.0 m/s².
How to find the Acceleration?We are given;
Force; F = 5 N
Acceleration of the first mass, a₁ = 8.0 m/s²
Acceleration of the second mass, a₂ = 24 m/s²
Formula for force is;
F = ma
Let us find both masses; m₁ and m₂.
m₁ = F/a₁
m₂ = F/a₂
Thus;
m₁ = 5/8 kg
m₂ = 5/24 kg
Total mass is; m = m₁ + m₂
m = 5/8 + 5/24
m = 15 + 5/24
m = 20/24 kg
Thus, acceleration if they are both tied together is;
a = F/m
a = 5/(20/24)
a = 6.0 m/s².

a. The voltmeter reads 0.053 volts
b. The electromotive force, emf of the battery is 0. 106 volts
How to determine the voltmeter reading
a. Given the current = 1. 15A
Voltmeter reads the voltage = V
Resistance could be gotten from the diagram = R
V = IR
To find the resistance from the structure
First, find the resistance in parallel
Resistance in parallel = 1/R1 = 1/R2 + 1/R3 = 1/25 + 1/15 + 1/15 = 0. 17 Ohms
Now, find the resistance in series
Resistance in series = R1 + R2 + R3 = 45 + 0. 17 + 10 = 55. 17 Ohms
Finally, the resistance in parallel = 1/35 + 1/55. 17 = 0. 028 + 0. 018 = 0. 046 Ohms
Substitute values into the equation
V = IR
V = 1. 15 * 0. 046
V = 0. 053 Volts
b. To find the Emf, use the formula
Emf = V + Ir
Substitute the values into the formula
Emf = 0. 053 + 1.15 * 0.046
Emf = 0. 053 + 0. 0529
Emf = 0. 106 volts
Therefore, the voltmeter reads 0.053 volts and the electromotive force of the battery us 0. 106 volts

To find the solution to your task, we will have to find 3/7 of 42, that is. How much is 3/7 of 42?
So, to find the value we must do the following way, multiply the value of the length of the fabric 42, by the numerator of the fraction 3 and divide by the denominator 7, See:
[tex]\begin{gathered}\Large\begin{array}{c}\tt\dfrac{3}{7}\:in\: 42\\\\ \tt 42\cdot 3=126\\\\ \tt 126\div 7=\boxed{\boxed{\tt 18}}\end{array}\end{gathered}[/tex]

Topic:Forces in equilibrium.
Answer:
.409 N
Explanation:
For this to balance, the moments around the fulcrum must sum to zero.
On the left you have .21 ( is that down? I will assume it is)
Counterclockwise moments :
.21 * 40 + 1.0 * 20
Clockwise moments :
.5 * 20 + F * 45
these moments must equal each other
.21*40 + 1 *20 = .5 * 20 + F * 45
F = .409 N

Questions: 1. A table of weight 500N has four legs covering a total area of 0.5m². Calculate the pressure applied by the table on the ground
2. A man with a mass of 50kg, is standing on the ground. His two feet cover an area of 0.01m². calculate the pressure exerted by his two feet
3. An elephant has a weight of 40000N and her feet cover a total area of 0.5m². A woman weighs 600N and area of her heels in contact with the ground is 0.0075m². Who exerts the greatest pressure on the ground?
Answer:
shown below
Explanation:
1) P = F/A
P = 500 / 0.5
P = 1000N/m²
2) W = mg
W = 50 x 9.8
W = 490
P = F/A
P = 490 / 0.01
P = 49000N/m²
3) P = F/A
For E:
P = 40000 / 0.5
P = 80000N/m²
For W:
P = 600 / 0.0075
P = 80000N/m²
They're exerting the same amount of pressure on the ground

A. pushing against a wall
B. babysitting
C. kicking a soccer ball
Answer:c
Explanation:work is force x distance. The wall doesn’t move any distance in A so that’s not work. B involves tasks that do work but I don’t think this is what they’re going for. For a short instance while kicking a ball, your foot is applying a force to the ball which moves a distance before following its own trajectory after contact with your foot. Because the contact has a short duration and isn’t instantaneous, this is work

Transparent materials passes light and they reflect also. The color filters are made by transparent or translucent materials. Thus option c is correct.
What is transparency?The ability of a material to pass light through it is called transparency. Some transparent materials can reflect the light. For example mirror, glasses etc. The materials which passes light but are not transparent is called translucent materials.
The material which does not pass light inside is called opaque. Wood, plastics etc. are opaque materials. Transparent covers, glasses make their inside visible.
Colour filters are made by transparent or translucent materials. They are used to filter or choose a particular colour from a group of reflected lights.

Alpha particles have highest mass.
Alpha particles are most ionising.

Beta particles are negatively charged.
Gamma particles have the highest speed.
Comparing the three types of ionizing radiation-alpha particles have the greatest mass. Alpha particles have approx 4 times the mass of a proton or neutron and 8,000 times the mass of a beta particle. Ionising power of alpha particle is very high due to double positive charge, large mass as compared to a beta particle. Alpha particles can cause multiple ionisations within a very small distance. Beta radiation is more penetrating than alpha radiation. beta radiation can pass through the skin, but it is absorbed by a few cm of tissue of the body or a few mm of aluminum. Gamma radiation is the most penetrating of the three radiations. Alpha particles are positively charged, while beta particles are negatively charged, and gamma radiation is electrically neutral. Gamma rays are similar to visible light but they have higher energy. Gamma rays are emitted along with alpha or beta particles during radioactive decay.learn more about gamma rays here:
