Answers

The answer of this is "Its surface composition"

Mars is the fourth planet from the Sun and the next planet beyond Earth. It is, on average, more than 142 million miles from the Sun.

Its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Red dust covers most of its surface. Mars has clouds and wind just like Earth. Sometimes the wind blows the red dust into a dust storm. Tiny dust storms can look like tornados, and large ones can be seen from Earth. Mars’ large storms sometimes cover the entire planet.

Mars has about one-third the gravity of Earth. A rock dropped on Mars would fall more slowly than a rock falls on Earth. A person who weighs 100 pounds on Earth would only weigh about 38 pounds on Mars because of the reduced gravity.

Answers

The distance of the travel covered within 5 hours with a speed of 120km/hr is the product of time and this speed and it is 600 km.

What is velocity?

Velocity of a substance is the measure of distance travelled per unit time. Thus it is the ratio of distance to time.In physics, velocity is the rate of speed.

Velocity = distance/time.

Hence, as the time taken for the travel increases velocity will decreases. The time given here is 5 hours and the speed of the vehicle is 120 km/hr. Hence, the distance can be calculated as follows:

Distance = time  × speed

               = 5 hr × 120 km/hr

Given

A ball is thrown from a 10 m high cliff at the velocity 20 ms-¹ with an angle of 30° to the horizontal plane as shown in the picture below. 40 m from the edge of the cliff is a 10 m high wall.

We have to determine

a) Will the ball pass over the wall?

b) If not, where will it hit the wall and with what velocity?

From the given information

Initial velocity v =20m/s

Initial velocity along x direction vx = vcos300

= 20 cos300

= 20 x 0.866

= 17.32m/s

Initial velocity along y direction vy = v sin300

= 20 sin300

= 20 x 0.5

= 10m/s

Displacement along +ve x = 40m

Time required to travel t = x/vx

= 40/17.32

= 2.31seconds

At this time displacement of the ball along the y direction

Sy = vyt – 1/2gdt2

= 10x2.31 – ½ x 9.81 x (2.31)2

= 23.10 – 26.17

= - 3.07m

Since displacement is in a negative value, it will hit the wall and will not pass over the wall

The ball will hit at d distance from the ground

H = (10 – 3.07)

= 6.93m

Final velocity along +ve y = v’y = vy –gt

= 10 – 9.81 x 2.31

= 10 – 22.66

=-12.66m/s

velocity along +ve x = v’y = vx

= 17.32m/s

So-net velocity of the ball v’= √((v^' x)^2+(v^' y)^2 )

= √(〖(17.32)〗^2+〖(-12.66)〗^2 )

= 21.45m/s

(a) The ball will not pass over the wall

Ignoring the effects of friction, what is the maximum elastic potential energy store of the ball when it is fully compressed after hitting the ground?​

Answers

The maximum elastic potential energy store of the ball when it is fully compressed after hitting the ground is 110 J

Since the effects of friction is ignored, there is no loss of energy as heat. So the entire elastic potential energy store of the ball is converted into kinetic energy store.

Elastic potential energy = Kinetic energy

Kinetic energy = 110 J

Elastic potential energy = 1 / 2 k x²

Kinetic energy = 1 / 2 m v²

k = Spring constant

x = Displacement

m = Mass

v = Velocity

If friction is ignored,

1 / 2 k x² = 1 / 2 m v²

v / x = √ ( k / m )

an air-filled parallel-plate capacitor has a capacitance of 1.5 pf. the separation of the plates is doubled and wax is inserted between them. the new capacitance is 3.0 pf. find the dielectric constant of the wax.

Answers

The dielectric constant of the wax is 2.

The dielectric constant of wax is the ratio of the capacitance of a capacitor that has wax between its plates to its capacitance when there is no wax between its plates.

This can be calculated by first finding the total capacitance of the capacitor with wax in between it:

C = 2 * pf * (0.5cm)^2

= 1.5 pf

Then, we can calculate the change in capacitance:

C' = C - C

= 2 pf * (0.5cm)^2 - 1.5 pf

if you toss a ball to your friends when the ball reaches its maximum altitude it’s vertical acceleration is what? is it 0 m/s or -9.81?

Answers

The vertical acceleration of the ball at its highest altitude is 0 m/s.

Has the acceleration ever been zero?

It is possible for an item to have both zero acceleration and non-zero velocity because acceleration is the change in velocity. Since there is no change in velocity while an object is moving at a constant speed, it experiences no acceleration.

At maximum height, is vertical velocity zero?

The bullet reaches its highest point when its vertical velocity is zero. The vertical portion of the velocity vector will now point downward. The projectile's horizontal range, which is determined by the object's beginning velocity, is referred to as the projectile's range.

What is the direction of acceleration at all points in the projectile's path?

Answers

For a projectile, the net force is the downward force of gravity; thus, the acceleration is downward. A downward acceleration could mean two things: the object is moving upward (has an upward velocity) and slowing down or the object is moving downward (has an downward velocity) and speeding up

Two nucleotides on the same strand form a __________ bond while two complimentary bases on opposite strands form ____________ bonds. An a-t base pairing forms _____ such bonds.

Answers

Two nucleotides on the same strand form a Phosphodiester bond while two complimentary bases on opposite strands form Hydrogen bonds. An a-t base pairing forms 2 such bonds.

In DNA double helix, the individual constituents are called nucleotides. These nucleotides are composed of bases which are linked together though covalent linkage also known as a phosphodiester bond.

Two individual strands in DNA are formed by the combination of phosphodiester linkages.

In general, with in a DNA nucleotides, hydrogen bonds are present which join the complementary pairs of bases. For example, two hydrogen bonds are present between thymine and adenine while three hydrogen bonds are present between cytosine and guanine.

What is potential energy?Potential energy is stored energy that depends on the relative positions of the various parts of the system. When a  spring is compressed, its potential energy is increased.A steel ball has more potential energy lifted off the ground than after it hits the ground. Potential energy is the energy stored in an object or matter. This stored energy is based on the position, placement, or state of an object or matter. Rocks at the edge of cliffs have potential energy. Potential energy is converted into kinetic energy when the stone falls. High branches of a tree have potential energy because they can fall to the ground.
