A bag weighing 20 N is pushed horizontally a distance of 35 m across a
level floor by a force of 10 N, How much work is done on the bag in
Joules? W=Fd *
Answer:
350J
Explanation:
Given parameters:
Weight of bag = 20N
Distance moved horizontally = 35m
Force applied = 10N
Unknown:
Work done on the bag = ?
Solution:
Work done is the force applied to move a body through given distance.
Work done = Force applied x distance
So;
Work done = 10 x 35 = 350J

Which equation should be used to calculate the speed of a wave?
speed = frequency x wavelength
speed = frequency x hertz
speed = period x wavelength
speed = period x hertz
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is the formula for wave speed?The speed of a wave is calculated by the equations: V = λ . f or V = λ/T, and the unit of measurement is m/s. This speed depends on the medium: in gaseous media, the speed is lower than in solid media.
See more about wave speed at brainly.com/question/10715783
The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.
What is Speed of wave?Wave speed is the movement of a progressive wave, which is an energy-moving disturbance that takes the shape of an oscillation and moves from one place to another.
The wavelength and frequency of a wave both affect its speed. A wave's speed is a crucial factor because it enables us to estimate how quickly the wave will disperse in the medium, which is the substance or material that will carry it.
This is the water in the case of ocean waves and the air in the case of sound waves. The kind of wave and the physical properties of the medium in which it is flowing also affect a wave's velocity.
Therefore, The equation should be used to calculate the speed of a wave is speed = frequency x wavelength.

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O . How many grams of water can be made from 64 g of oxygen gas?
Answer: 144 g
the mol of the oxygen gas is 64/16 = 4 (mol)
we have:
2H2 + O2 => 2H2O
4 ------> 8
=> the mol of H2O is 8 mol
=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)

The time for a sound wave to travel between two people is 0.80 s,
The people are 256 m apart
Calculate the speed of sound in air.
Answer:
Explanation:
Using the below formula
Speed of sound = ( distance between observers) *2/(total time taken)
Now putt the given values ,
time taken = 0.80 sec
distance = 256 m
hence
V of sound= 256*2/0.80
V of sound = 640 m/sec
when a chemical reaction occurs, chemical bonds ______ break and new chemical bonds form to create the __________
Answer:
a) reactant
b) product
Explanation:
During a chemical reaction, the reactants interact among themselves in a specific temperature, pressure, pH, enzyme etc. Due to various intra and inter molecular and atomic interactions, the chemical bonds in the reactants break down. Formation of new chemical product is governed by the formation of new bond (ionic, covalent, hydrogen vander waal etc. )

How does the sun maintain its high temperature and energy output?
Answer:
The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). ... The core is the only part of the sun that produces an appreciable amount of heat through fusion.
Explanation:
I got you
By not running out of fuel (Hydrogen).
Rest assured ... When the sun runs low on Hydrogen, it'll go through several complex changes, and it'll end up at much much lower temperature, with much much lower energy output.

Can an object with acceleration of zero be in motion?
Answer:
NO
Explanation:
if it has no acceleration then it's not moving
Answer:
Yes when the velocity is constant then the acceleration is said to be zero. Thus an object with 0 acceleration can be in motion.
Let me give you an example to make you more clear
Example:
When a car is traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.

Equation of motion description is v=20+2t.How big is the initial speed,acceleration?
Answer:
the initial velocity is 20 m/s and the acceleration is 2 m/s²
Explanation:
Given equation of motion, v = 20 + 2t
If V represents the final velocity of the object, then the initial velocity and acceleration of the object is calculated as follows;
From first kinematic equation;
v = u + at
where;
v is the final velocity
u is the initial velocity
a is the acceleration
t is time of motion
If we compare (v = u + at) to (v = 20 + 2t)
then, u = 20 and
a = 2
Therefore, the initial velocity is 20 m/s and the acceleration is 2 m/s²

which statements describe kinetic and potential energy? check all that apply.
Answer:
ACDE
Explanation:
Energy is generally described as the ability to do work by a body. There are two main forms of energy which are the kinetic energy and the potential energy.
Other energy forms stems from these two energy types.
Potential energy expressly deals with the position of a body. It is mathematically given as:Potential energy = mass x acceleration due to gravity x height
It is the energy stored based on the position of particles within a mediumThese description satisfies options A, C
Kinetic energy is the energy due to the motion of body. It is mathematically given as:Kinetic energy = [tex]\frac{1}{2}[/tex] x mass x velocity²
Also, kinetic energy is directly proportional to the velocity of a body.The description satisfies DE

Find the electric field E⃗ (r⃗ )E→(r→)E_vec(r_vec) inside the sphere (for rrr< aaa) in terms of the position vector r⃗ r→r_vec. Express your answer in terms of r⃗ r→r_vec, rhorhorho (Greek letter rho), and ϵ0ϵ0epsilon_0.
Solution :
Using the Gauss law, the electric field intensity of a sphere is given by :
[tex]$E. 4 \pi r^2 = \frac{Q_{enc}}{\epsilon_0}$[/tex]
[tex]$E = \frac{Q_{enc}}{4 \pi r^2 \epsilon_0}$[/tex]
Now the enclosed charge inside the sphere (r<a) is
[tex]$Q_{enc}= \rho V$[/tex]
[tex]$Q_{enc}= \rho \left( \frac{4}{3} \pi r^3 \right)$[/tex]
Hence, the electric field intensity becomes as follows :
[tex]$E= \frac{\rho \left(\frac{4}{3} \pi r^3\right)}{4 \pi \epsilon_0 r^2}$[/tex]
[tex]$E =\frac{\rho r}{3 \epsilon_0}$[/tex]
Thus, the electric field inside the sphere is given by :
[tex]$\vec {E} = \frac{\rho \vec{r}}{3 \epsilon_0}$[/tex]
