Grasshoppers
Wolves
Mushrooms

Answers

Answer 1

Answer:

Answer:

grasshopper

Explanation:

because they eat the plants

I am not sure if its is that tho it may be mushrooms

Answer 2

Answer: grasshoppers. they eat plants.

Answer:

The rate of reaction increases to counter the action of removing heat.

Explanation:

The reaction between zinc and hydrogen chloride produces zinc chloride, hydrogen gas, and heat.
The reaction is exothermic reaction. Heat is produced in the reaction.
It means the temperature of system increase when reaction proceeds. When heat is removed from system, it stimulates the reaction to fast to produce more heat.
Due to fast reaction rate of reaction increases.

A 1,500-kg car is moving at a speed of 10 m/s. What is the car's kinetic energy?

Answers

Kinetic Energy of particle of mass, m moving with velocity, v is

K.E. = ½mv²

m= 1500 kg

v = 10 m/s

((1/2)*1500)* $10^(2)$

750*10=75000

KE=75 joules

How can you figure out kinetic energy?

According to classical physics, kinetic energy (KE) is determined by multiplying an object's mass by its velocity squared, or half of the mass (1/2*m). The kinetic energy of an object with a mass of 10 kilograms (m = 10 kg) travelling at a speed of 5 m/s (v = 5 m/s) is equal to 125 joules, or (1/2 * 10 kg) * 5 m/s2.

a vehicle with a mass of 1200 kg and a speed of 20 m/s. KE = ½mv 2

KE = ½ x 1200 x (400) = 240,000 J 2.

Hello!

If The 1500 kg car will increase its velocity to 10 m/s. What Will be its kinetic energy ?

We have the following data:

m (mass) = 1500 kg

v (velocity) = 10 m/s

KE (kinetic Energy) = ? (in Joule)

Formula to calculate kinetic energy:

$\boxed{KE = (1)/(2) *m*v^2}$

Solving:

$KE = (1)/(2) *m*v^2$

$KE = (1)/(2) *1500*10^2$

$KE = (1)/(2) *1500*100$

$KE = (150000)/(2)$

$\boxed{\boxed{KE = 75000\:Joule}}\:or\:\boxed{\boxed{KE = 75\:kJ}}\Longleftarrow(kinetic\:energy)\:\:\:\:\:\:\bf\blue{\checkmark}$

What are chemical properties of water?

Answers

The chemical property of water is oxidane. Water is tasteless, odorless at a normal temperature. Etc.

Water is covalently bonded (H-O-H). All simple covalent molecules such as these have low melting and boilong points. Water does not conduct electricity. It reacts with a lot of elements, especially vigorously with alkali metals

Isotopes called what are used to diagnose disease and to study environmental conditions
