why do these planets not support life?
The thin atmosphere of Mars is thought to be due to the planet's lack of a magnetic field, which has allowed the Solar wind to blow away much of the gas the planet once had. Venus, despite still having a thick atmosphere of CO2, surprisingly has a similar problem

A Ball A and a Ball B collide elastically. The initial momentum of Ball A is 14.0kgm/s and the initial momentum of Ball B is -9.00kgm/s. Ball A has a mass of 2.00kg and is traveling at -5.00 m/s after the collision. What is the velocity of ball B if it has a mass of 3.00kg
The total momentum before collision is
14.0 kg•m/s + (-9.00 kg•m/s) = 5.00 kg•m/s
If v is the velocity of ball B after colliding with ball A, the total momentum after collision is
(2.00 kg) (-5.00 m/s) + (3.00 kg) v
Momentum is conserved, so these quantities are equal. Solve for v :
5.00 kg•m/s = (2.00 kg) (-5.0 m/s) + (3.00 kg) v
5.00 kg•m/s = -10.0 kg•m/s + (3.00 kg) v
15.0 kg•m/s = (3.00 kg) v
v = (15.0 kg•m/s) / (3.00 kg) = 5.00 m/s
Two students are observing the motion of a Mercedes Benz. They calculate, with various handy dandy gadgets, that the Benz is changing its speed constantly by 2.2 m/s every second while moving along a straight road.
Student 1: The Benz is traveling at a constant velocity. Therefore at the end of 2 seconds it's speed will still be 2.2 m/s.
Student 2: No, the Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.
Which student do you agree with and why? Discuss all parts of all statements made by both students. Saying I agree with student 1 or 2 or neither will not suffice.
Student 2 is correct. The Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.
Final velocity of the Benz
The final velocity of the benz is determined by using first kinematic equation;
v = u + at
where;
u is the initial velocitya is the final velocity = (2.2 m/s) / 1s = 2.2 m/s²t is the timev = 2.2 + (2.2 x 2)
v = 6.6 m/s
Change in velocityΔv = 6.6 m/s - 2.2 m/s = 4.4 m/s
Thus, student 2 is correct. The Benz is not traveling at constant velocity. At the end of two seconds the speed would have increased by 4.4 m/s.

A car travels for 2 hours at a speed of 55 km/h. calculate the distance traveled
This is a uniform rectilinear motion (MRU) exercise.
We get the data:

To calculate the distance, multiply the speed by the time.
d = v * t
d = 55km/h * 2hr = 110kmThe distance traveled is 110 km.

a. 50 n
b. 15 n
c. 25 n
d. 100 n
The magnitude of the force of friction between the crate and floor is 50 N.
Magnitude of the force of friction
The magnitude of the force of friction is determined from Newton's second law of motion.
F - Ff = ma
Ff = F - ma
Ff = 200 - (20 x 7.5)
Ff = 50 N
Thus, the magnitude of the force of friction between the crate and floor is 50 N.

Which telescopes must be placed in orbit around earth in order to observe short-wavelength radiation?.
Space telescopes must be placed in orbit around earth in order to observe short-wavelength radiation.
What is telescope?A telescope is an optical instrument that uses lenses, curved mirrors, or a combination of both to watch distant objects.
When atoms in a gas reach this temperature, they travel so quickly that when they collide, they release X-ray photons with wavelengths smaller than 10 nanometers.
Because the Earth's atmosphere prevents all X-rays from space, these wavelengths must be seen using space telescopes.
To study short-wavelength radiation, space telescopes must be put in orbit around the Earth.
Hence, space telescope is the correct answer.

Ultrasound was used to check for cracks in an aeroplane wing. The ultrasound pulse would be reflected from any cracks and from the end of the wing. The diagram shows the oscilloscope trace produced by the echo. How far along the wing was the crack? The speed of sound in metal is 5000m/s.
The depth of the crack along the aeroplane wing is determined as 1.5 m.
Depth of the echo reflection
The depth of the crack in the wing from which the echo is heard is calculated as follows;
d = (vt)/2
From the image;
time 1 = 0.4 mstime 2 = 0.8 msd1 = (5000 x 0.4 x 10⁻³)/2
d1 = 1 m
d2 = (5000 x 0.8 x 10⁻³)/(2)
d2 = 2 m
Average depth
d = (d1 + d2)/2
d = (1 + 2)/2
d = 1.5 m
Thus, the depth of the crack along the aeroplane wing is determined as 1.5 m.

A child pulls on a wagon with a force of if the wagon moves a total of in what is the average power delivered by the child?
Given the force exerted by the child to pull the Wagon through the given distance and time, the average power delivered by the child is 16.9 Watts.
This question is incomplete, the complete question is:
A child pulls on a wagon with a force of 75N. If the wagon moves a total of 42m in 3.1min, what is the average power delivered by the child?
What is Power?Power is simply the amount of energy transferred or converted per unit time.
It is expressed as;
P = W/t
Where W is work done and t is time elapsed.
But Work done is expressed as;
W = F × d
Where F is force applied and d is distance covered.
Hence;
Power = W/t = Fd / t
Given that;
Force exerted F = 75N = 75kgm/s²Distance covered d = 42mTime elapsed t = 3.1min = ( 3.1 × 60)s = 186sAverage power delivered P = ?Power = Fd / t
Power = ( 75kgm/s² × 42m ) / 186s
Power = (3150kgm²/s²) / 186s
Power = 16.9 kgm²/s³
Power = 16.9 Watts
Given the force exerted by the child to pull the Wagon through the given distance and time, the average power delivered by the child is 16.9 Watts.
