A backpack weighs 8.2 Newtons and has a mass of 5 kilograms on the moon what is the strength of gravity on the moon
i dont get it so much but
The weight of the bag pack is 8.2 N. g = 1.64 m/s2. Hence, the acceleration due to gravity on moon is 1.64 m/s2. sooo? is it right

Explanation:
If a 2 kg ball is moving at 6 m/s to the right and then hits a wall and bounces back at - 4 m/s (left), what is the change in momentum (in kg*m/s)?
Answer:
The change in momentum (in kg*m/s) [tex]= 20[/tex]
Explanation:
The change in momentum is equal to
Final Momentum - Initial Momentum
As we know
Momentum is equal to the product of mass and velocity
M = m * v
Thus, change in momentum
[tex]m_2v_2 - m_1v_1[/tex]
here m1 = m2 = 2 Kg
Substituting the given values in above equation we get -
[tex]2 * 6 -( 2 *-4)\\12 + 8 = 20[/tex]kg m/s

All materials are made up of elements. Which of the following best describes elements? A. Mixtures combine in several different ways to make many kinds of elements. B. Elements are unable to combine in order to make different compounds. Elements combine in several different ways to make many kinds of compounds. > D. Compounds combine in several different ways to make a limited number of elements,
Answer:
a.
Explanation:
Answer:
I am pretty sure it is C!
Explanation:
According to www.open.edu,
Elements are substances that are made from one type of atom.
Compounds are substances made from atoms of different elements joined by chemical bonds.
A mixture is made by simply mixing together elements and compounds.
Atoms are the basic building blocks.
i think A is incorrect because, while the statement may be correct, it is talking about Mixtures, not elements themselves!
B is incorrect because elements ARE able to combine to form compounds!
D is incorrect because ELEMENTS combine to create compounds, i am pretty sure compounds don't combine to create elements.

A rocket is fired at 60 to the horizontal with an initial speed of 200m5 calculate it time of flight and it range on the horizontal plane
Answer:
See answer below
Explanation:
In order to do this, we just need to apply the expression to determine the time of flight. This is given by:
t = 2 V₀ Sinθ / g (1)
We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:
t = 2 * 200 Sin60° / 9.8
t = 35.348 sNow that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:
X = V * t (2)
We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:
X = 200 cos60° * 35.348
X = 100 * 35.348
X = 3534.8 mHope this helps
A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of the loop in which the plane is flying?
Answer:
The radius of the curve is 9,183.67 m.
Explanation:
Given;
velocity of the jet plane, v = 600 m/s
acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²
The radius of the curve is calculated from centripetal acceleration formula as given below;
[tex]a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m[/tex]
Therefore, the radius of the curve is 9,183.67 m.

what causes lightning?
Answer:
cause by imbalances between stroms cloud and grounds , or within the cloud themselves.
Explanation:
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.
The positive and negative charges grow large enough, a giant spark lightning, occurs between the two charges within the cloud.
What is lightning?The naturally occurring electrostatic discharge with high voltage for short duration from the cloud to the ground or within the cloud. The lightning can be seen by a flash of light that could be followed by the strong sound. Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground or within the clouds. In the starting stages air acts as an insulator, but after the charges build up with the charges in the ground and cloud there will be the rapid form of electricity causes lightning. These lightning were in the color of bluish white.
Thus, the charges discharging naturally causes lightning.

Two objects of mass 5 kg and 8 kg at rest F1 and F2 meters force applied on both the boxes respectively If the speed of both the objects after 5 sec become 16m/s and 15m/s respectively find the value of F1 and F2?
Answer:
F1 = 16 N and F2 = 24 N
Explanation:
Formula used => F = m×a and v-u= at
So, as we know force = mass × acc.
so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now
Here u= 0 as the objects are placed at rest initially..
thus, v= at
FOR 1ST BLOCK
16= <math> F1/5 </math> × 5 ==> F1 = 16 N
FOR 2ND BLOCK
15= <math> F2/ 8 </math> × 5 ==> F2= 24 N
(a) If a person can jump a maximum horizontal distance (by using a 45° projection angle) of 3.0 m on Earth, what would be his maximum range on the Moon, where the free-fall acceleration is g/6 and g 5 9.80 m/s2 ? (b) Repeat for Mars, where the acceleration due to gravity is 0.38g.
Answer:
See explanation
Explanation:
Range of a projectile is given by; U^2sin2θ/g
When θ = 45°
The maximum range is obtained as;
Rmax = U^2/g
Maximum range on earth = RME = U^2/g
Maximum range in the moon= RMM =U^2/g/6
Maximum range in Mars = RMMA = U^2/0.38g
a)
RME/RMM = U^2/g/U^2/g/6
RME/RMM = 6
But RME = 3 m
RMM = 3 * 6 = 18 m
b)
RME/RMMA =U^2/g/U^2/0.38g
RME/RMMA = 1/0.38
But RME = 3 m
RMMA = 3/0.38
RMMA = 7.9 m

hope my answer helps
Explanation:
second law of reflection states that the angle of incidence equals to the angle of reflection,

observe the wave it emits in the window. Change the speed of the motion of the electron. What
relationship do you notice between speed and wavelength?
Answer:
The wavelength decreases as the electron speeds up. The wavelength increases as the electron slows down.

An airplane traveling at 201 m/s makes a turn. What is the smallest radius of the circular path (in km) that the pilot can make and keep the centripetal acceleration under 5.0 m/s2 ?
Answer:
the smallest radius of the circular path is 8.1 km
Explanation:
The computation of the smallest radius of the circular path is given below:
Given that
V = Velocity = 201 m/s
a_c = acceleration = 5 m/s^2
radius = ?
As we know that
a_c = V^2 ÷ r
5 = 201^2 ÷ r
r = 201^2 ÷ 5
= 8,080.2 g
= 8.1 km
Hence, the smallest radius of the circular path is 8.1 km
