Calculate the weight of an object of 30 kg on Earth. 2. Calculate the weight of an object of 30000 g on Earth. 3. Calculate the

Dima020 [189]

Answer:

1. 294N

2. 294N

3. 19.6N

4. 19.6N

5. 4.9N

6. 4.9N

7. 80N

8. 185N

Explanation:

The weight of an object is the force that gravity is having over it, and we measure it in <u>Neutowns (N), which equals Kg x m/s².</u>

To find the weight of an object, we use the formula F= m x g.

F stands for force, m for the object's mass, and g for gravity, which is the force that attracts objects to Earth, and we measure it by the acceleration that an object has during free falling.

<u>The Earth's gravity is 9.8 m/s²</u>

1. We use the formula F=m x g

F= 30kg x 9.8 m/s²

F= 294 N

2. We have to convert the 30000g into kg to use the formula

30000÷1000= 30kg

30000g equals to 30Kg, so the object's mass (m) is 30Kg.

F= m X g

F= 30kg X 9.8 m/s²

F= 294 N

3. F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

4.We have to convert the 2000g into Kg.

2000÷1000= 2Kg

The object's mass (m) is 2Kg.

F= m X g

F= 2kg X 9.8 m/s²

F= 19.6 N

5. F= m X g

F= 0.5 kg X 9.8 m/s²

F= 4.9 N

6.We have to convert 500g to Kg.

500g÷1000=0.5Kg

The object's mass (m) is 0.5 kg

F= m X g

F= 0.5 Kg X 9.8 m/s²

F= 4.9 N

7. The gravity on the moon is different from the one on Earth. In the formula, instead of 9.8 m/s² for the gravity (g), we use 1.6 m/s².

F= m X g

F= 50Kg X 1.6m/s²

F= 80N

8. The gravity (g) on Mars is 3.7 m/s², so we have to use it in the formula where it says g to find the object's weight on Mars

F= 50Kg X 3.7m/s²

F= 185 N

How does the virus use a host cell to make copies of itself

vagabundo [1.1K]

Answer:

I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.

If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).

In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.

In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

In an experiment, the membrane potential of a neuron is hyperpolarized to –120 mV. When an inhibitory neurotransmitter is applie

denis-greek [22]

Answer:

The inhibitory transmitter activates ligand-gated potassium channels

Explanation:

When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.

However, with the addition of inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium gated channels, which were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.
