Answer:
Explanation:
Force Mass * acceleration
F = ma
a = F/m
Sum of force = 16.3N - 15.8N = 0.5N
Mass = 0.62kg
Substitute
a = 0.5/ * 0.62
a = 0.81m/s²
The acceleration of the toy is 0.81m/s²
the unit of mass is fundamental unit

Geosphere
Hydrosphere
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

Which newton's law would best go with doing push ups?
Answer:
Newton's Third Law
Explanation:
According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.
Answer: 8.1m/s^2
Explanation:
For this question, in order to solve it, we have to use the second equation of motion which will be:
s = ut + 1/2at^2
where,
u = initial velocity
v = final velocity
t = time
a = acceleration
Since u = 0, then
a = 2s/t^2
a = 2 × 110/5.21^2
a = 220/27.1441
a = 8.1m/s^2

Calculate the following sum, and express the answer in meters. Follow the rules for significant figures.
(25.873 km) + (1024 m) + (3.0 cm) =
Answer:
26897.3 m
Explanation:
1 km = 1000 m
1 cm = 0.01 m
so the calculation will be
25873 m + 1024 m + 0.03 m= 26897.3 m
The sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters) would be 26897.0 meters.
What are significant figures?In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.
As given in the problem we have to Calculate the following sum and express the answer in meters, by Following the rules for significant figures,
(25.873 kilometers ) + (1024 meters ) + (3.0 centimeters)
1 kilometers = 1000 meters
1 meter =100 centimeters
(25.873 ×1000×100) + (1024×100 ) + (3.0 centimeters)
= 26897.03 centimeters
Thus ,the sum of the given expression (25.873 kilometers ) + (1024 meters ) + (3.0 centimeters) would be 26897.0 meters.

A toy car with mass of 3.0kg is push along the table .If the net force on the book is 15.0N what is the toy car's accelaration?
Answer:
a = 5
Explanation:
F = M × A
15 = 3 × a
a = 15 / 3
a = 5
This is only if the toy can is pushing the book or smth coz the question looks incomplete...?
Answer:
5 m/s^2
Explanation:
Realize that Newton's Second Law explains that the net force is equal to the mass mulitplied by the acceleration, or in simple terms, F=ma. In the problem, the force is 15 newtons, and the mass is 3 kg. Substiting and dividing, we get 5 m/s^2 (5 meters per second squared).
Omar wrote a hypothesis about batteries called dry cells. If more dry cells are connected end to end, a light bulb will work longer because there is more energy available. What are the variables in his hypothesis? The independent variable is the number of dry cells, and the dependent variable is the length of time the bulb works. The independent variable is the length of time the bulb works, and the dependent variable is the number of dry cells. The independent variable is the number of dry cells, and the dependent variable is the amount of energy available. The independent variable is the amount of energy available, and the dependent variable is the number of dry cells.
Answer:
The independent variable is the number of dry cells and the dependent variable is the time the bulb works.
Explanation:
In this exercise, you are asked to analyze the variables derived from Ómar's hypotypeis
"If more dry cells are connected end-to-end, a light bulb will work longer because more energy is available."
In this hypothesis, the independent variable that is controlled by the researcher is the number of batteries to be connected in series.
The dependent variable that is measured by the researcher is how long the bulbs last.
When reviewing the different answers, the correct one is:
The independent variable is the number of dry cells and the dependent variable is the time the bulb works.
