Answer:
d. 12.30 grams
Explanation:
Given the following data;
Force = 652 N
Acceleration = 53 m/s²
To find how much the object weigh, we would need to determine its mass;
Force = mass * acceleration
652 = mass * 53
Mass = 652/53
Mass = 12.30 grams.
Therefore, the object weighs 12.30 grams.

The photograph shows one of the boats in a science club's toy boat race. All the boats were powered by identical
rubber bands. Judges used stopwatches to time how long each rubber band took to unwind. The table shows some
of the data the judges collected.
Answer: Boat P
Explanation:
Multiple all of them mass times acceleration and which ever one was the greatest was the answer. Which was Boat P 0.2436
The minimum time taken to unwind the rubberband is by boat P.
The highest amount of force to unwind the rubberband is generated by boat P.
Force, Mass and AccelerationThe table shows all the mass, acceleration and time of each boat. To unwind the rubber band, the required force can be calculated as given below.
Force = Mass [tex]\times[/tex] Acceleration
For boat N, force is [tex]f_n = 0.125\times 1.6 = 0.2 \;\rm N[/tex]
For boat P, force is [tex]f_p = 0.116\times 2.1 = 0.24 \;\rm N[/tex]
For boat Q, force is [tex]f_q = 0.130\times 1.0 = 0.13 \;\rm N[/tex]
For boat R, force is [tex]f_r = 0.118\times 1.8 = 0.21 \;\rm N[/tex]
Hence we can conclude that the highest amount of force to unwind the rubberband is generated by boat P.

Para el siguiente conjunto de medidas, calcule EL ERROR RELATIVO PORCENTUAL: 1.34 m, 1.35 m, 1.37 m y 1.36 m
Answer:
Ver explicacion abajo
Explanation:
En este caso para poder calcular el error relativo porcentual, es necesario calcular primero el error absoluto, que se calcula de la siguiente forma:
Error absoluto = Resultado exacto - aproximación
Sin embargo, no tenemos el resultado exacto de las medidas, pero podriamos conocerlo tomando el promedio de estas medidas y este es el que tomaremos como el verdadero resultado de las medidas:
Promedio de medidas = 1.34 + 1.35 + 1.37 + 1.36 / 4
Promedio de medidas = 1.355 m
Ya que tenemos el promedio, podemos calcular el error absoluto de cada medida y luego el error relativo porcentual:
Ea1 = 1.355 - 1.34 = 0.015
Ea2 = 1.355 - 1.35 = 0.005
Ea3 = 1.37 - 1.355 = 0.015
Ea4 = 1.36 - 1.355 = 0.005
Ya que tenemos los 4 errores absolutos, es posible calcular el porcentual:
%error relativo = (Error absoluto / resultado exacto) * 100
Aplicando la expresión con cada uno de los valores tenemos:
%Er1 = (0.015/1.34) * 100 = 1.12%
%Er2 = (0.005/1.35) * 100 = 0.37%
%Er3 = (0.015/1.37) * 100 = 1.09%
%Er4 = (0.005/1.36) * 100 = 0.37%
Espero que te sirva.

Explanation:
Calculate acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds.
Answer:
acceleration = 0.013 m/s²
Explanation:
formula for acceleration is
a = (v-u) / t
a= (0.7-0.3) / 30
= 0.013
The acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²
Acceleration is defined as the change in velocity of a body with respect to time. Mathematically:
[tex]a=\frac{v-u}{t}[/tex]
v is the final speed = 0.7m/s
u is the initial speed = 0.3m/s
t is the time taken = 30seconds
Substitute the given values into the formula:
[tex]a=\frac{0.7-0.3}{30}\\a=\frac{0.4}{30}\\a = 0.0133m/s^2[/tex]
Hence the acceleration of a turtle going from 0.3 m/s to 0.7 m/s in 30 seconds is 0.0133m/s²

Please help me answer this, I'm so clueless!
Answer:
More carbon dioxide or greenhouse gases in the atmosphere can lead to global warming. Oceans store a large amount of heat, and increases in sea surface temperature can increases the amount of water vapor over the oceans, and that will increases the amount of greenhouse gases.
A7 lb bowling ball accelerates at a rate of 7 m/s2. If the net force on the bowling ball is
tripled, what will be its new acceleration? (1 point)
a. 2.3 m/s2
b. 7 m/s2
c. 14 m/s2
d. 21 m/s2
Answer: c
Explanation:
If the net force on the bowling ball is tripled, its new acceleration is 21 m/s². The correct option is d.
What is force?The force is the action of push or pull which can move or stop the object.
The initial force is F = mass x acceleration
F = 3.17515 kg x 7 m/s²
F = 22.23 N
When the net force is tripled, the new acceleration will b e
3 x F =m x a'
3 x 22.23 = 3.17515 x a'
a' = 21.003 m/s²
Thus, the new acceleration is 21 m/s². The correct option is d.

Which waves have oscillations parallel to their direction of motion
Answer:
The direction of these oscillations is the difference between longitudinal or transverse waves. In longitudinal waves, the vibrations are parallel to the direction of wave travel. In transverse waves, the vibrations are at right angles to the direction of wave travel.
Explanation:
The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.
What are sound waves?A sound wave is the wave that shows the disturbance patterns that should be lead by the movement of the energy that should be travelled via the medium like air, water, since it should be propagated away from the sound source.
Therefore, The waves that contains the oscillations parallel to their direction of motion should be considered as the sound waves from stereo speaker.

A negative charge of -3.0 x 10^-5 C is placed 0.35 m from a positive charge of 9.0 x 10^-5 C. What is the force between the two charges
Answer:
the force between the two charges is 198.37 N
Explanation:
Given;
charge of the first particle, Q₁ = -3 x 10⁻⁵ C
charge of the second particle, Q₂ = 9.0 x 10⁻⁵ C
distance between the two charges, r = 0.35 m

Answer:
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

you push a freezer with a force of 250 N. if you move it a distance of 15 m, how much work was done?
Answer:
375J
Explanation:
W=F x d
=250 x 15
=375J
The work W is equal to the force f times the distance d, or W = fd, to mathematically describe this idea. If the force is applied at an angle to the displacement, the work is W = fd cos.
What force is related to work done?Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, For a constant force that is oriented in the same direction as the motion, it is easiest expressed as the product of the force's magnitude and the distance travelled.
A desk is being subjected to applied force if someone is pushing it across the room. The person's force applied to the desk is known as the applied force.
