Answer;
-Single replacement
Explanation;
The reaction;
Cu(s) + 2AgNO3= Cu(NO3)2 + 2Ag , is an example of a single replacement reaction.
-It is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound.
In the above reaction copper(Cu) takes the place of silver(Ag) in the salt AgNO3 to form Copper (ii) nitrate (CuNO3) and silver metal (Ag).
- Another example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free.
Answer:
10
Explanation:
But you have to be fat though lol
Answer:
Explanation:
The y component of the force is 100 sinØ . But given that y component is 30N
so 100 sinØ = 30
sinØ = 0.3
Ø = 17.5°.
X component of force = 100 cosØ
= 100 cos17.5
= 95.35 N .
Y component of force = 30 N .
Angle Ø = 17.5°.
Answer:
∵ 
Explanation:
The tangential acceleration of a cart moving at a constant speed in a circle is:
The angular velocity is constant when the circular speed is constant.
We know that the (instantaneous) tangential velocity of such object is given by:
Now for angular acceleration we have a constant angular speed:
And angular acceleration is related to tangential acceleration as:
Answer:
Icy roads
Explanation:
There is so little friction you slide on it way more than other roads. :)
