Answer: Both of the compounds contain primary bonding; however, the bonding is of different types. Magnesium chloride (MgCl₂) contains ionic bonds, which are stronger and involve the complete transfer of electrons. Meanwhile, ethane (C₂H₆) also bonds by electron transfer but the electrons are not completely transferred from one atom to another. Instead, they are shared, forming what is known as a covalent bond.
mass of the cart?
a. 80N
b. 80 kg
C. 20 N
d. 20 kg
The mass of cart pushed by a 40 Newton force moving with an acceleration of 0.5 m/s² is 80 Kg.
In order to move a body ofmass 'm'kg with an acceleration of 'a' m/s², a force of magnitude → |F| = ma is needed to push the body in a specified direction.
Given is a cart pushed by a 40 Newton force moving with an acceleration of 0.5 m/s².
Mass of block = m Kg [assume]
Force on cart [F] = 40 N
Acceleration of cart [a] =0.5 m/s²
From the definition of force -
|F| = ma
m = |F|/a
m = 40 / 0.5
m = 80 kg
Therefore, the mass of cart pushed by a 40 Newton force moving with an acceleration of 0.5 m/s² is 80 Kg.

Answer:
In summer season, sun would not set at latitude 66.5 N and above. In summer season for southern hemisphere, sun would not set for latitude 66.5 S and above.
Explanation:
Season on Earth occurs due to the inclination of the axis about which it rotates. Due to this, there is different length of day and night in different hemispheres at a time.
Sun is highest in the sky in northern hemisphere in summers. So the places at 66.5 N and higher latitude experience 24 hours sun light.
Similarly, in northern hemisphere summers, places at 66.5 S and higher latitude experience 24 hours sun light.
The sun not set in the summer and greater than 66 N
I hope that's help !
Answer:
(a) 200.0628 N ; ( b) 4.08Kg
Explanation:
We know,
w = mg [here w= weight , m= mass , g= gravity]
now,
gravity on earth (g) =9.807 m/s²
mass of the spanner (m)=?
weight of the spanner on earth(w) = 40N
⇒ w = 40N
⇒m g =40N
⇒m = (40/g) Kg
⇒m= (40/9.807)Kg
∴m=4.08Kg
∴mass of the spanner on earth = 4.08Kg
We know,
Mass is the amount of matter in an object . Somass will remain same both on earth and jupiter.
So,
(b)The mass of the spanner on jupiter = 4.08Kg
Now,
The mass of the spanner on jupitar (m) = 4.08Kg
Gravity on jupiter (g*) = 5.g [5 times on earth]
= 5 . (9.807)m/s²
=49.035 m/s²
(a)
∴weight of the spanner on jupitar(w*) = m g*
=(4.08 x 49.035) N
=200.0628 N
Answer:
milk
Explanation:
it is not a pure substance
milk does is a colloid
oxygen is an element and H20 and CO2 are compounds so they are pure
Answer:
migration
