The pressure between two costs is proportional to the product of the charges.
If solely one of the expenses is decreased by way of a element of 3, then the pressure is decreased with the aid of a thing of 3.
If each prices are reduced by a thing of 3, then the pressure is reduced via a issue of 9.
Answer:
either +z direction or -z direction.
Explanation:
The direction of the electric field, in an electromagnetic wave always is perpendicular to the direction of the magnetic field and the direction of propagation of the wave.
You assume a system of coordinates with the negative x axis as the west direction, and the y axis as the up direction
In this case, the wave is propagating toward the west (- x direction), and the magnetic field vector points up (+ y direction), then, it is mandatory that the electric field vector points either +z direction or -z direction.
If the mass of an object doubles, the weight of the object also doubles
If the mass of an object halves, the weight of the object also halves
Explanation:
The mass of an object is an intrinsec property of the object that gives a measure of the "amount of matter" in the object. Mass is indipendent from the location of the object.
On the contrary, weight gives a measure of the force of gravitational attraction felt by the object in a gravitational field. Weight is dependent on the location.
The mass and the weight of an object are related by the following equation:
where:
W is the weight of the object
m is its mass
g is the acceleration of gravity
We see from the formula that the weight of an object is directly proportional to its mass. This means the following:
- If the mass of an object doubles, the weight of the object also doubles
- If the mass of an object halves, the weight of the object also halves

Answer:
B or D
Explanation:
I wanna say B but I don't really know if it's a trick question
my explanation for D is that anvils are usually 110 decibles and ear drums usually are damaged when exposed to 82dbs or higher at a consistant rate so I'd imagine that'd be the answer I hoped this helped
Answer:
80 N
Explanation:
From the question,
F = ma .......................... Equation 1
Where F = Force, m = mass of the object, a = acceleration of the object.
make m the subject of the equation
m = F/a.................... Equation 2
Given: F = 24 N, a = 3 m/s²
Substitute into equation 2
m = 24/3
m = 8 kg.
If the acceleration of the object becomes 10 m/s²,
Substitute into equation 1
F = 10(8)
F = 80 N.
