Explanation:

Answer/Explanation:

The weight of an object is defined as the force that is exerted due to the gravitational force.

Mathematically, it can be written as :

W = m g

Where

m is the mass of the object

g is the acceleration due to gravity

Also,  

We know that the value of g varies with respect to the location. At the equator, the value of g is less as compared to the poles.

The feature of an object that affects its weight are :

Mass of the object

Location of the object

How much force Earth exerts on the object

Answer:

hydrochloric acid

Explanation:

The compound Mr. Pham's company used is most likely hydrochloric acid.

Hydrochloric acid is a strong acid and it is applied to remove corrosion and rusts from another body.

The acid is capable of dissolving and breaking down the rust and corrosion.

A base does not have this property and would not effectively remove the corrosion.

Sodium hydroxide and lithium hydroxide are bases.

Nitric acid is not as strong as hydrochloric acid.

Answer:

i) 2Mg + O₂ + Δ Heat → 2MgO + Δ Energy

ii) The aqueous solution does not change in the color of the blue litmus paper and the blue litmus paper remains blue in color

The aqueous solution formed using the product (MgO) turns the red litmus paper blue

Explanation:

i) Magnesium easily burns in air or oxygen when heated to form a white powder of magnesium oxide. The burning (reaction) of magnesium in air is an exothermic reaction that involves the release of heat and light

The burning of magnesium wire is given by the following chemical reaction;

2Mg + O₂ + Δ Heat → 2MgO + Δ Energy

ii) When magnesium oxide is mixed with water if forms magnesium hydroxide Mg(OH)₂ as shown in the following chemical reaction;

MgO + H₂O → Mg(OH)₂

Magnesium hydroxide is basic and therefore it will turn red litmus paper blue and it does not change the color of the blue litmus paper.

Answer:

periodic motion

Explanation:

The massive object is affectionately referred to as the pendulum bob. When the bob is displaced from equilibrium and then released, it begins its back and forth vibration about its fixed equilibrium position. The motion is regular and repeating, an example of periodic motion.

Answer:

Doing work' is a way of transferring energy from one object to another, energy is transferred when a force moves through a distance.

Explanation:  So more energy, more work done bc u transferred more energy to move the object and doing the work. and if you only use a little of energy, the work done also only a little.

Answer:

The velocity of the cricket ball is 17.32 m/s

Time is taken by the ball to reach the highest point = 0.8660 seconds

Explanation:

The cricket ball can be seen and treated as a projectile in this case

The maximum height attained by a projectile in motion can be calculated using the formula:

[tex]h = \frac{v^2 sin^2 \theta }{2g}[/tex]

In any projectile problem, once we know see that the object was released vertically upwards, we need to know that this means that the angle of projection is 90 degrees, and sin 90 is = 1

hence, h will be modified to become

[tex]h = \frac{v^2 }{2g}[/tex]

[tex]v = \sqrt{2gh}[/tex]

We are given that h = 15m and g = 10m/s2

[tex]v = \sqrt{2 \times 10 \times 15} = 17.32m/s[/tex]

The velocity of the cricket ball is 17.32 m/s

B. We can get the time it took to reach the highest point by dividing

time = distance/speed

Time = 15/17.32 = 0.8660 seconds

Answer: The molecules in gases are different from other states of matter

Explanation:

The molecules in gases are different from other states of matter because unlike, for example, a solid, they move around freely and are much more spread apart. A gas can fill up any container, but once the container is unsealed, the gasses will immedietly be let out. Gases can be compressed much more easily than a solid or a liquid.

Given

mass of sled m=5 kg

Elevation [tex]\theta =45^{\circ}[/tex]

[tex]\mu _k=0.185[/tex] (coefficient of kinetic friction)

Friction will oppose the motion of the sled while sled weight sin component helps it to move down the incline

[tex]W\sin\theta-F_r=ma\\where\\W=weight(mg)\\F_r=Friction(\mu_kmg\cos\theta)\\a=acceleration[/tex]

Substituting values

[tex]mg\sin \theta-\mu_kmgcos\theta=ma\\g\sin \theta-\mu_kg\cos \theta=a\\a=g(\sin 45^{\circ}-0.185\times \cos 45^{\circ})\\a=5.64\ m/s^2[/tex]

Explanation:

Answer:

plane

Explanation:

Answer:

3040 m

Explanation:

The formula to apply here is ;

d=∅*r  where

d is the diameter of the spot , ?

∅ is angle of divergence in radians, = 0.8 * 10⁻⁵rad

r is distance of Moon from Earth, =380,000 km

Applying the formula as;

d=∅*r

d= {0.8 *10⁻⁵} * 380,000 * 1000

d= 3040 m

Answer:

0.55 m/s².

Explanation:

From the question given above, the following data were obtained:

Mass (m) of ball = 2 Kg

Force (F) applied = 1.1 N

Acceleration (a) =?

Force (F) is defined as the product of mass (m) and acceleration (a). Mathematically, the force (F) can be represented as:

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can calculate the acceleration of the ball as follow:

Mass (m) of ball = 2 Kg

Force (F) applied = 1.1 N

Acceleration (a) =?

F = ma

1.1 = 2 × a

Divide both side by 2

a = 1.1 / 2

a = 0.55 m/s²

Therefore, the acceleration of the ball is 0.55 m/s²

Answer:

75km/hr

Explanation:

distance(d)=150km

time(t)=2hours

speed=distance/time

Answer:

See the answers below. And the free body diagrams attached.

Explanation:

To solve this problem, we must build a free body diagram, where we show the forces acting on a body, first for the m2 body, where the force of 3.5 [N] acts to the right. In such a way that a reaction force is presented in the opposite direction due to the string tied between both bodies, we will call this force T1.

Now using Newton's second law, which is defined as the sum of forces equal to the product of mass by acceleration, we can determine an equation as a function of T1.

∑F = m*a

[tex]3.5 -T_{1}=0.6*a_{2}[/tex]

We have an equation with two unknowns, in such a way we must perform a second free body diagram for the body with mass m1, to acquire the additional equation.

∑F =m₁*a₁

[tex]T_{1}=0.4*a_{1}[/tex]

By kinematics we know that if the string tied to Body 2 moves a distance, the part of the string at the end tied to body 1 will move the same distance. This same analysis is valid for velocities and accelerations.

This is the accelerations a1 and a2 are equal. Now equalizing both equations.

[tex]3.5-0.4*a_{1}=0.6*a_{2}\\but\\a_{1}=a_{2}\\3.5-0.4*a_{1}=0.6*a_{1}\\a_{1}=3.5[m/s^{2} ][/tex]

The acceleration of each block connected by the given string is 3.5 m/s².

The given parameters;

The net force on the blocks is calculated as follows;

[tex]\Sigma F = ma\\\\F - T = m_2a\\\\F - m_1(a -g)= m_2a\\\\g = 0 \ , \ in \ horizontal \ direction\\\\F - m_1a = m_2 a\\\\F = m_2 a + m_1 a\\\\F = a(m_1 + m_2)\\\\a = \frac{F}{m_1 + m_2} \\\\a = \frac{3.5 }{0.4 + 0.6} \\\\a = 3.5 \ m/s^2[/tex]

Thus, the acceleration of each block connected by the given string is 3.5 m/s².

This question appear incomplete

Explanation:

This question appear incomplete because of the absence of options. However, metamorphic rocks are rocks that are formed from other pre-existing rocks under heat and pressure (both are usually high), causing them to twist and melt together. Metamorphism simply means a change in form of something and that's what happens here also.
