The water hyacinth lives in lakes and ponds it forms large floating mats of plants because it does not root in soil which adaptation lets it get nutrients directly from the water is it A.1 curly leaves B.Trailing C.Sturdy stems D. Upright flowers

Answers

Answer:

C. Sturdy stems

Explanation:

Sturdy stems is the adaptation that enables water hyacinth to get nutrients directly from the water because there is no roots are present for the absorption of nutrients from water. The hollow bulbous stem below each leaf of water hyacinth allows the plant to get nutrients from the water. This hollow bulbous stem allow the plants to float on the water surface, keeping the leaves and flowers above the water so they don't rot.

Every second, the Sun converts about 600 million tons of hydrogen into 596 million tons of helium. The remaining 4 million tons of mass is Every second, the Sun converts about 600 million tons of hydrogen into 596 million tons of helium. The remaining 4 million tons of mass is converted to an amount of energy equal to 4 million tons times the speed of light cubed. converted to an amount of energy equal to 4 million tons times the speed of light. reabsorbed as molecular hydrogen. converted to an amount of energy equal to 4 million tons times the speed of light squared. ejected into space in a solar wind.

Answers

Answer:

Converted to an amount of energy equal to 4 million tons times the speed of light squared. ejected into space in a solar wind.

Explanation:

The 4 million tons of mass is converted to the amount of energy that is equal to 4 million tons times the speed of light squared. This energy moves from the sun with the help of solar winds and received by the planets present in the solar system. This solar energy moves in the form of solar radiation because there is no medium for propagation so that's why we can say that the mass is converted into energy that moves in the form of radiation in discrete packets.

A 7 cm thick and 20 cm long wedge is used to pierce a 3cm long log of diameter 20cm what is the velocity ratio of the wedge

Answers

Answer:

The velocity ratio of the wedge is 0.15

Explanation:

Use the following formula to calculate the velocity ratio

Velocity Ratio = Distance Moved by effort / Distance moved by Load

Where

Distance Moved by effort = 3cm

Distance moved by Load = 20 cm

Placing values in the formula

Velocity Ratio = 3cm / 20 cm

Velocity Ratio = 0.15

A person can lands safely on the surface of the earth but not moon. why?​

Answers

Answer:

The gravitational force on the moon is less than on Earth, because the strength of gravity is determined by an objects' mass. The bigger the object, the bigger the gravitational force. Gravity is pretty much everywhere

Explanation:

Why might astronauts choose to “lope” or hop rather than walking or running on the moon? Astronauts can “lope” in the moon's low gravity levels, even though this gait pattern is very difficult to use on Earth.

Explanation:

An endothermic reaction is any reaction in which energy is absorbed by the reaction system.Thus implies that energy is withdrawn from the environment A cold pack's function is based on an endothermic chemical reaction.

The absorption of energy by the reaction system means that the environment feels cool in an endothermic reaction.This manifests in a decrease in the temperature of the cold pack.

B. An echo

Explanation:

An echo is the sound heard after the reflection of sound waves from a hard surface. It has both advantages and disadvantages with respect to its applications.

Some of it applications include;

i. it can be used to determine the depth of the sea

ii. it can be used in crude oil exploration

iii. it can be used to determine the speed of sound in air

An echo is different to reverberation of sound.

What is the electric field strenght in units of N/C if the flux through a 2.0m by 1.0m rectangular surface is 396Nm2/C, if the electric field is uniform, and if the plane of the surface is at an angle of π/3 radians with respect to the direction of the field ?

Answers

Answer:

The appropriate answer is "396 N/C".

Explanation:

The give values are:

Rectangular surface,

[tex]\Phi_e=396 \ N.m^2/C[/tex]

[tex]a = 2 \ m[/tex]

[tex]b = 1 \ m[/tex]

Angle,

[tex]\theta =\frac{\pi}{3} \ radian[/tex]

Now,

The area of rectangle (A) will be:

=  [tex]a\times b[/tex]

=  [tex]2\times 1[/tex]

=  [tex]2 \ m^2[/tex]

hence,

The electric field strength will be:

⇒  [tex]\Phi_e=E.A Cos \theta[/tex]

or,

⇒  [tex]E=\frac{\Phi_e}{ACos \theta}[/tex]

On putting the given values, we get

⇒      [tex]=\frac{396}{2\times Cos(\frac{\pi}{3} )}[/tex]

⇒      [tex]=\frac{396}{2\times 0.5}[/tex]

⇒      [tex]=\frac{396}{1}[/tex]

⇒      [tex]=396 \ N/C[/tex]

Which type of uninterruptible power supply uses AC power to continuously charge its battery, while also providing power to devices through the battery?

Answers

Answer:

An online UPS.

Explanation:

An online UPS is a type of uninterruptible power supply uses AC power to continuously charge its battery, while also providing power to devices through the battery. It combines the inverter and rectifier to provide power to the alternating current (AC) load while supplying alternating current (AC) power during an outage to the load through the inverter.

Basically, an uninterruptible power supply unit is used to provide constant power supply to an electrical device, especially during a power outage.
