If you stood on mars and lifted a 15kg pack, you would be pulling with a force greater than...?
Pls i need help and I will give brainliest to the best explained answer :)
Answers
Answer:
See the answers below
Explanation:
In this problem, we must be clear about the concept of weight. Weight is defined as the product of mass by gravitational acceleration.
We must be clear that the mass is always preserved, that is, the mass of 15 [kg] will always be the same regardless of the planet where they are.
[tex]W=m*g[/tex]
where:
W = weight [N] (units of Newtons)
m = mass = 15 [kg]
g = gravity acceleration [m/s²]
Since we have 9 places with different gravitational acceleration, then we calculate the weight in each of these nine places.
Mercury
[tex]w_{mercury} = 15*3.8\\w_{mercury}= 57 [N]\\[/tex]
Venus
[tex]w_{venus}=15*8.8\\w_{venus}= 132 [N][/tex]
Moon
[tex]w_{moon}=15*1.6\\w_{moon}=24[N][/tex]
Mars
[tex]w_{mars}=15*3.7\\w_{mars}=55.5 [N][/tex]
Jupiter
[tex]w_{jupiter}=15*23.1\\w_{jupiter}= 346.5[N][/tex]
Saturn
[tex]w_{saturn}=15*9\\w_{saturn}=135[N][/tex]
Uranus
[tex]w_{uranus}=15*8.7\\w_{uranus}=130.5[N][/tex]
Neptune
[tex]w_{neptune}=15*11\\w_{neptune}=165[N][/tex]
Pluto
[tex]w_{pluto}=15*0.6\\w_{pluto}=9[N][/tex]

Which statement best explains why light can travel with or without a medium?
A medium is necessary for light waves to travel.
Light waves cannot travel in a vacuum.
Light waves are longitudinal waves that do not require a medium to travel.
Transverse waves do not require a medium to travel.
Answers
Answer:
Transverse Waves do not require a medium to travel
Explanation:
Two major types of energy waves are longitudinal waves and transverse waves. A longitudinal wave is a wave where the particles of matter in the medium move in a parallel direction to the motion of the wave. This shows the energy transport and particle movement. The particles of matter only move temporarily. A wave is transferred energy it does not transfer particles of matter. A transverse wave is a wave in which the particles of matter in the medium move in a perpendicular direction to the motion of the wave.
Answer:
Transverse waves do not require a medium to travel.
Explanation:
which of the following is not an example transverse wave?
1) X-rays
2) Ocean waves
3) Microwaves

true or false. because the speed of an object can change from one instant to the next, dividing the distance covered by the time of travel gives constant speed
Answers
true. Because the speed of an object can change from one instant to the next, dividing the total distance covered by the time of travel gives. average speed.
Answer:
False.
Explanation:
Dividing the distance covered by the time would give us the average speed, not a constant speed. Constant speed exists only if the speed of an object does not change.

5. A force probe is used to pull the block with a constant speed. The probe measures a force of
1.8 N. What is the size of the friction force you are pulling with? Explain how you came up
with this answer.
Answers
Answer:
Frictional Force = 1.8 N
Explanation:
From Newton's Second Law, we know that the acceleration is produced in an object, whenever an unbalanced force is applied to it. So, for the production of acceleration application of an unbalanced force is necessary. Since, the block is moving with uniform speed in this case. Therefore, there is no acceleration involved in the motion of block. So, the all the forces acting on the block must cancel the effect of each other. So, that there is no unbalanced force to produce any acceleration. Therefore, the frictional force must be equal to the applied force in order to cancel its effect and balance it.
Frictional Force = Applied Force
Frictional Force = 1.8 N

A 2.5. Gram arrow enters a 100 g apple with a speed of 115 m/s. If the apple was originally at rest, then what speed will it have as the arrow enters it? Remember the formula is P=MxV
Answers
Answer:
The speed of the apple will be 2.81 m/s when the arrow enters it.
Explanation:
We can find the speed of the apple by conservation of linear momentum:
[tex] p_{i} = p_{f} [/tex]
[tex] m_{ap}v_{ap_{i}} + m_{a}v_{a_{i}} = m_{ap}v_{ap_{f}} + m_{a}v_{a_{f}} [/tex]
Where:
[tex]m_{ap}[/tex] is the mass of the apple = 100 g = 0.1 kg
[tex]m_{a}[/tex] is the mass of the arrow = 2.5 g = 0.0025 kg
[tex]v_{ap_{i}}[/tex] and [tex]v_{ap_{f}}[/tex] is the initial and final speed of the apple respectively
[tex]v_{a_{i}}[/tex] and [tex]v_{a_{f}}[/tex] is the initial and final speed of the arrow respectively
Since the apple was originally at rest ([tex]v_{ap_{i}}[/tex] = 0) and knowing that [tex]v_{a_{f}}[/tex] = [tex]v_{ap_{f}}[/tex] when the arrow enters into the apple, we have:
[tex] 0 + 0.0025 kg*115 m/s = v(0.0025 kg + 0.1 kg) [/tex]
[tex]v = 2.81 m/s[/tex]
Therefore, the speed of the apple will be 2.81 m/s when the arrow enters it.

a 3.5 kg mass has an initial velocity of 4.0 m/s. How much force is required to increase the velocity of the mass to 8.0 m/s in 3.0 seconds?
Answers
Answer:
4.67 N of force are required
Explanation:
The second Newton's law states the net force exerted on a body of mass m that has an acceleration a, is given by:
F=m.a
On the other hand, the kinematics equations relate the acceleration with the change of speed over time, expressed as:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
We are given the initial speed of vo=4 m/s on a mass of m=3.5 Kg, the final speed of vf=8 m/s which took t=3 seconds.
The acceleration is:
[tex]\displaystyle a=\frac{8-4}{3}=1.33[/tex]
[tex]a=1.33\ m/s^2[/tex]
Thus, the force is:
[tex]F=3.5\ Kg\cdot 1.33\ m/s^2[/tex]
[tex]F=4.67\ N[/tex]
4.67 N of force are required
A 2.00 kg ball is thrown upward at some unknown angle from
the top of a 20.0 m high building. If the initial magnitude of the
velocity of the ball is 20.0 m/s. What is the value of total
energy?
Answers
Answer: 792J
Explanation:
The value of the total energy will be "792 Joules". To undestand the calculation, check below.
Energy and VelocityAccording to the question,
Mass of ball, m = 2.0 kg
Building's height, h = 20.0 m
Ball's initial velocity, v = 20.0 m/s
We know the formula,
Potential energy (U) = mgh
Kinetic energy (K) = [tex]\frac{1}{2}[/tex] mv²
and,
The total energy be:
= U + K
= mgh + [tex]\frac{1}{2}[/tex] mv²
By substituting the values,
= 2.00 × 9.8 × 20.0 + [tex]\frac{1}{2}[/tex] × 2.00 × (20.0)²
= 392 + 400
= 792 Joules
Thus the above answer is correct.

Medical technologists are developing a new type of pacemaker that, when planted inside a human’s chest, uses electrical impulses to help keep a steady heartbeat. The new design will send warning signals to a patient’s hospital sooner when it detects an upcoming heart problem. In testing so far, this new feature has only worked in about 25% of test patients. How does this product most likely need to be improved before doctors can report that the new technological design is successful? The product needs to better solve the problem for which it was designed. The product needs to become available to the public more quickly. The product needs to become more time effective when it is being built. The product needs to make better use of available building materials.

After testing the new technology on patients and it showed only 25% success rate ( very low success rate). It is concluded that before Doctors can report that the new technology design is successful is when it better solves the problem for which it was designed for ( i.e. increase in the success rate to > 50% ). because for a procedure to be considered successful for deployment it will need to record a success rate of over 50% of the test patients.
Therefore the product needs to better solve the problem for which it was designed
