The first hominine in the genus Homo was named Homo habilis because evidence indicates that members of the species used

Answers

Homo Habilis was a secies of the tribe Hominini, which lived between 2.4 and 1.5 million years ago. His name means "handy man" or "able man". Homo habilis was short, with disproportionately long arms compared to modern humans. His remains are often acompanied by primitive stone tools. Answer: The species was nemed because evidence indicates that members of the spieces used stone tools.

If I was 14 stone what would my gravity be on venus

Answers

The acceleration of gravity on the surface of Venus (8.87 m/s^2) is 90.4% (rounded) of its value on Earth's surface (9.807 m/s^2). So if your weight on Earth is exactly 14 stone, then you would weigh 12st 9.2lb (rounded) on Venus.

What is the specific heat of an unknown substance if 2000 J of energy are required to raise the temperature of 4 grams of the substance 5 degrees Celsius?

Answers

The energy required to heat a substance is related by the formula:
Q = mCpΔT ; where Q is the energy, m is the mass of the substance, Cp is the specific heat capacity and ΔT is the change in temperature.
2000 = (4)(Cp)(5)
Cp = 100 Joules / g °C

15. A ball attached to a string is being swung in a clockwise circular path as shown in Figure 3-1. In which directionwill the acceleration on the ball be when the ball passes point A?
a. direction a
b. direction b
c. direction c
d. direction d

Answers

A ball attached to a string is being swung in a clockwise circular path as shown in Figure 3-1. direction will the acceleration on the ball be when the ball passes point A is direction a. Hence option A is correct.

Angular velocity is "rate of change of angular displacement with respect to time". i.e. ω= dθ/dt. it is also defined as angular displacement over time. i.e. ω = angular displacement/Time.

Angular velocity shows how much angle can be covered in unit time. It's SI unit rad/s. direction of the Agular velocity is given by right hand thumb rule.

Angular acceleration is rate of change of Angular velocity with respect to time.

i.e. α = dω/dt if an object changes its angular velocity in short time, we can say that it has greater angular acceleration. It is expressed in rad/s².
