5N to the left. This is because Jeremy pushes 10 to the left but Amanda does 5, making 5 of the 10 go away. This leaves 5 to the left. So... The answer is C.
Sorry if this is a little confusing to read I’m trying to answer it best I can without being confusing

Its letter C. 5N to the left. Since Jeremy's force in Newtons are higher than Amanda's (in newtons), and since Jeremy's force directs to the left, then the direction of the force will be to the LEFT. Then subtract the higher one to the lower one so that would be: 10N-5N=5N. So it is C. 5N to the left.

If the load distance of a lever is 30 cm and the effort distance is 60 cm, calculate the amount of effort required to lift a loa
vladimir2022 [97]

Here,

Load distance (Ld) = 30 cm

Effort distance (Ed) = 60 cm

Load (L) = 200N

Effort (E) = ?

Now, By using formula,

or, E * Ed = L * Ld

or, E * 60 = 200 * 30

or, E = 6000/60

◆ E = 100N

This is a Right answer...

I hope you understand...

The tendency of an atom to attract electrons towards itself is called
SVEN [57.7K]

Answer:

Electronegativity

Explanation:

Element: <em>An element is a substance which can not be split into simpler units by an ordinary chemical process</em>

Electronegativity: This is the power of an atom in a molecule to attract electrons. The electronegativity of an element increase across the period in the periodic table and decreases down the group. The most electronegative elements are the reactive non metals.

Examples of electronnegative element include, Oxygen, Chlorine, Fluorine, Nitrogen, sulphur etc.

Mass and energy are alternate aspects of a single entity called mass-energy. The relationship between these two physical quantit
Sever21 [200]

Answer:

Explanation:

ΔE = Δm × c^2

where,

ΔE = change in energy released with respect to change in mass

= 1.554 × 10^3 kJ

= 1.554 × 10^6 J

Δm = change in mass

c = the speed of light.

= 3 × 10^8 m/s

Equation of the reaction:

2H2 + O2 --> 2H2O

Mass change in this process, Δm = 1.554 × 10^6/(3 × 10^8)^2

= 1.727 × 10^-11 kg

The change in mass calculated from Einstein equation is small that its effect on formation of product will be negligible. Hence, law of conservation of mass holds correct for chemical reactions.
